Dennis Birkholz 95c41da020 Cache readFilter access and skip inner loops for empty/default readFilter (#773) 
For large XLSX files `Reader/Xlsx::readColumnsAndRowsAttributes()` performs
a lot of calls to `$this->getReadFilter()` and `$this->getReadFilter()->readCell()`
as `readCell()` is called twice for each (possibbly filled) cell.

By ignoring calls to the DefaultReadFilter implementation (which always returns true),
using no custom read filter will not incur any runtime penalty.

The runtime penaltiy when using a custom read filter is reduced by a third by
caching the read filter into a variable instead of using the getter method.

Fixes issue #772.

Write generated HTML into Mpdf in chunks, rather than as one gigantic string 
Due to a limitation in Mpdf, the HTML string passed to its WriteHTML method
must not exceed a particular length. PhpSpreadsheet produces one HTML string
containing all spreadsheet data when writing to HTML, which can easily exceed
Mpdf's size limit. Thus, it was impossible to write large spreadsheets to PDF
using the Mpdf writer - this change fixes that issue.

OFFSET should allow omitted height and width 
Commit 8dddf56 inadvertently removed the ability to omit the width
and height arguments to the OFFSET function. And #REF! is returned
because the function is validating that the new $pCell argument
is present. It is present, but it has been passed in the $height position.

We fixed this by always passing $pCell at the last position and filling
missing arguments with NULL values.
