Please explain your intent
Currently fpdf2 supports 4 compression methods for images:
https://github.com/py-pdf/fpdf2/blob/2.8.0/fpdf/image_parsing.py#L35

The PDF standard specification (cf. PDF32000_2008.pdf section 7.4 Filters) defines several other compression filters, including LZWDecode.

Recently, this filter was implemented by @MartinThoma in our companion library pypdf: py-pdf/pypdf#2883

Describe the solution you'd like
Support LZWDecode for images compression.
