MATCH with a static array should return the position of the found value based on the values submitted.
Returns #N/A, unless the element searched for is at the end of the array.

The problem is in Calculation.php line 4231:
                    if (!is_array($functionCall)) {
                        foreach ($args as &$arg) {
                            $arg = Functions::flattenSingleValue($arg);
                        }
                        unset($arg);
                    }

I believe this code is intended to handle functions where PhpSpreadsheet just passes
the call on to PHP without implementing the code on its own, e.g. for atan or acos.
In the bug report, the following code fails:
  $flat_rate = "=MATCH(6,{4,5,6,2}, 0)";
  $sheet->getCell('A1')->setValue($flat_rate);
The expected value is 3, but the actual result is "#N/A".
The reason for this result is that the parser replaces the braces with calls
to the MKMATRIX internal function, whose value for functioncall was:
'self::MKMATRIX'. Since this isn't an array, the flattening code is executed,
and the unintended result occurs. The fix is to change the definition for
functioncall in that case to [__CLASS__, 'mkMatrix'], avoiding the flattening.

However, there is also another part to this bug. The flattening should be
returning the first entry in the array, but is in fact returning the last.
This explains why the bug report specified "unless ... end of the array".
I confirmed that Excel does use the first item in the array rather than the last,
e.g. =atan({1,2,3}) entered into a cell will return atan(1), not atan(3).
The problem here is that flattenSingleValue, which says in its comments that
it is supposed to be returning the first item, uses array_pop rather than array_shift.
I have changed that as well. The same mistake was also present in
Cell.php function getCalculatedValue. The correct behavior can be verified
by entering =minverse({-2.5,1.5;2,-1}) into an Excel cell'
Excel flattens the result ({2,3;4,5}) to 2, and so should PhpSpreadsheet.

Fix removing last row incorrect behavior
`$highestRow = $this->getHighestDataRow();` was calculated after `$this->getCellCollection()->removeRow($pRow + $r);` - this is the root reason for incorrect rows removal because removing last row will change '$this->getHighestDataRow()' value, but removing row from the middle will not change it. So, removing last row causes incorrect `$highestRow` value that is used for wiping out empty rows from the bottom of the table:
```php
for ($r = 0; $r < $pNumRows; ++$r) {
    $this->getCellCollection()->removeRow($highestRow);
    --$highestRow;
}
```
To prevent this incorrect behavior I've moved highest row calculation before row removal.
But this still doesn't solve another problem when trying remove non existing rows: in this case the code above will remove `$pNumRows` rows from below of the table, e.g. if `$highestRow=4` and `$pNumRows=6`, than rows 4, 3, 2, 1, 0, -1 will be deleted. Obviously, this is not good, that is why I've added `$removedRowsCounter` to fix this issue.
And finally, moved Exception to early if statement to get away from unnecessary 'if-else'.

Claas Augner ffb0d21cec PHPDoc: use @return $this for fluent methods
Fluent methods, especially setters, return the object on which are
called. This is documented in PHPDoc using the `$this` keyword, which
is equivalent to `static` with the additional notion of object identity.
This helps IDEs and static analysis tools provide more meaningful output.

Fix active cell when freeze pane is used
When freeze pane is in use on a worksheet, PhpSpreadsheet saves to Xlsx in such
a way that the active cell is always set to the top left cell below the freeze
pane. I find it difficult to understand why:

  1. You have given users the setSelectedCells function, but then choose to
     ignore it.
  2. Excel itself does not act in this manner.
  3. PHPExcel did not act in this manner.
  4. PhpSpreadsheet when writing to Xls does not act in this manner.
     This is especially emphasized because the one test in FreezePaneTest which
     would expose the difference is the only test in that member which is
     not made for both Xls and Xlsx.
  5. It is *really* useful to be able to open a spreadsheet anywhere, even when
     it has header rows.

Modify XLSX RW to keep decimal for floats with a zero decimal part
Prior to 1.10, all numeric values where read as floats. In 1.10
numeric values are read using 0 + x, which relies on PHP type
juggling rules. As a result, float(0.0) is written as string('0'),
then read back as int(0). This fix causes the writer to retain the
the decimal for float values such that a reader can differentiate
floats from ints.

Fix infinite loop when reading invalid ODS files
According to the spec, http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part1.html#__RefHeading__1415588_253892949,
a `<table:table-row>` can only ever contains a `<table:table-cell>` or
a `<table:covered-table-cell>`, but it seems that some invalid files in the wild
may contains something else. That would trigger an infinite loop. So instead we
totally ignore the invalid content.

Closes #832

Use gt operator instead of max for highest row
Using an operator is significantly faster than calling the max function.
As this method is called more than once per cell the difference adds up.

Remove duplicate strtoupper
Removing the duplicate strtoupper call has a meaningful impact on
performance since this method is called at least once per cell.

`Worksheet::getCells` currently calls `strtoupper` twice. `strtoupper`
is kind of expensive and this method is called at least once for every
cell in the spreadsheet.  By removing the unnecessary second call the
runtime decreases by 18% when importing a ~100K cell spreadsheet.
