Column indexes are always based on 1 everywhere in PhpSpreadsheet.
This is consistent with rows starting at 1, as well as Excel
function `COLUMN()`. It should also make it easier to reason about
columns and rows and remove any doubts whether a specific method is
expecting 0 based or 1 based indexes.

This allow to create and configure the standard instance of the
external PDF libary, before returning it to the standard writer.
Or, more powerful, this allow to provide a custom implementation
of the external PDF library, allowing for custom behaviors. An
example of that would something like: https://tcpdf.org/examples/example_003/Closes#266
Previously the function did not check whether the return value of `ZipArchive::locateName`
was `false`. And when it was, it was passed straight into `ZipArchive::getFromIndex`,
which casts it to an integer, resulting in it incorrectly retrieving the entry at index `0`.

When describing a cell, the cell reference (r="A1") is optional.
When not present, we should just increment the index of the last processed row.

When the xml file is not a standard xml file, the `simplexml_load_string` will return false, this will cause an error on "$xml->getNamespaces(true);" . So instead of showing the error, we throw an exception.
Control characters in cell values are automatically escaped without
the need to excplicitly call `StringHelper::buildCharacterSets()` beforehand.
Fixes#212
Array keys used for styling have been standardized for a more coherent experience.
It now uses the same wording and casing as the getter and setter methods.
Closes#189
Add option to suppress validation of sheet titles
Based on a "lowest common denominator" approach to compatibility,
we will continue to enforce a 31-character limit for sheet titles.
However, this limit should not be enforced when loading an existing
file.
Added a new optional parameter to Worksheet::setTitle() and
Worksheet::setCodeName() to suppress validation and massaging,
based on the premise that existing files should be given a
best-effort approach to loading and parsing. Unfortunately, it's
not possible with the current architecture to prevent users from
making use of this functionality, aside from with a strongly-worded
warning.
Added test coverage. I didn't see any existing unit tests of the
Worksheet class, so I created a new test to cover these methods.
Fixes#176
Third party PDF libraries must now be installed via composer and naturally
via composer autoloading mechanism. Because of that it is not necessary
to specify their path on disk. The usage is simplified and it allows us
to include them in our unit tests.
This also means that from now on PhpSpreadsheet must use composer autoloader
mechanism. The internal autoloading implementation was dropped.
