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`.

We used to have some kind of wrapper that didn't do much except
forward methods to the real instance. That unnecessary complexity
made it harder to work with the real writer instance.
Temporary directory set to PDF writer is passed to mPDF object in constructor.
mPDF 7.0 changed temporary directory configuration from constant to constructor parameter.
Without this change it is not possible to change default temporary directory.

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
The static variable $imageCounter previously had a constant value of 0 throughout the program as it was never being modified, because it was commented out by mistake.
Now it increments every time a new drawing is being instantiated.
This also fixed a problem when multiple images of same name in the same worksheet are incorrectly displayed.

As described in http://interoperability.blob.core.windows.net/files/MS-XLS/[MS-XLS].pdf
a relative column reference can be between -255 +255 and not -127 + 127, the column
index should be read as a signed int16.
