PyMuPDF changed method names

[DPDmancul]

PyMuPDF had changed method names form CamelCase to snake_case: https://pymupdf.readthedocs.io/en/latest/znames.html Now with PyMuPDF 1.19.x some warnings are shown, but then starting from 1.20.0 the CamelCase nomenclature will be missing.

[DPDmancul]

This should fix it:
