Deprecation Warning from Pillow

[michaeltraxler]

The used library Pillow seems to change and it might be necessary to react?

brother_ql_web.py:120: DeprecationWarning: multiline_textsize is deprecated and will be removed in Pillow 10 (2023-07-01). Use multiline_textbbox instead.
textsize = draw.multiline_textsize(text, font=im_font)

[FriedrichFroebel]

As Pillow 10 has been published, this might actually be a hard error in some systems: https://pillow.readthedocs.io/en/stable/deprecations.html#font-size-and-offset-methods

When doing some changes on my personal fork with some custom features, I fixed this as well (this the solution the Pillow developers recommend as well): FriedrichFroebel@17dbdf1#diff-de421af0299c557fa29364d4cc862f1da261c17cf0a962aae9036772208257fdL119-R123 Due to this repository appearing unmaintained from Philipp's side, I currently do not have any plans to create a corresponding PR.
