Bumps pypdfium2 from 4.28.0 to 4.30.0.

Release notes

Sourced from pypdfium2's releases.

4.30.0

Changes (Release 4.30.0)

Summary (pypdfium2)

Backported bug fixes / corrections from current development branch to preferably leave v4 in a clean state.

• Fixed blunder in PdfImage.extract() producing an incorrect output path for prefixes containing a dot. In the extract-images CLI, this caused all output images of a type to be written to the same path for a document containing a non-extension dot in the filename.
• XFA / rendering CLI: Fixed incorrect recognition of document length. pdf.init_forms() must be called before len(pdf).
• Made get_text_range() allocation adapt to pdfium version, as FPDFText_GetText() has been reverted to UCS-2. (See v4.28 changelog for background.)
• Updated workflows to include both macos-13 and macos-14 in test matrices because v13 is Intel and v14 ARM64 on GH actions. Removed python 3.7 testing because not supported anymore on macos-14 runners.
