`master` is now the only permanent branch. Features and fixes should be merged
into `master` when stable. Pull requests should be forked from `master`.
`develop` branch disappear entirely in favor of temporary features/fixes branches.

- Added calculation engine support for the new complex number functions that were added in MS Excel 2013
- IMCOSH() Returns the hyperbolic cosine of a complex number
- IMCOT() Returns the cotangent of a complex number
- IMCSC() Returns the cosecant of a complex number
- IMCSCH() Returns the hyperbolic cosecant of a complex number

Passing 0 arguments will throw the following error:
"PHP Fatal error: Uncaught ArgumentCountError: Too few arguments to function PhpOffice\PhpSpreadsheet\Spreadsheet::getSheet(), 0 passed in {filepath} and exactly 1 expected"
The \PhpOffice\PhpSpreadsheet\Shared\Date class has support for setting an alternate timezone which affects the conversion of Excel Date timestamps in PhpSpreadsheet. This amendment is an effort to document this support.
The behavior is similar to what is done in LibreOffice. That means if there is a
comment it will be shown with a small indicator and the actual comment will be
revealed when mouse hover over the indicator.
Fixes#308Closes#310
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
