Pull request overview

Fixes uncaught exceptions during LocalInputSource initialization so PDF inputs that FPDI can’t parse (e.g., unsupported compression) don’t prevent creating an input source, aligning with issue #205’s request to bypass local PDF handling failures.

Changes:

• Add a regression test asserting pageCount becomes null when encountering an unsupported PDF (e.g., XfaForm.pdf).
• Broaden constructor exception handling to avoid failing LocalInputSource creation when PDF parsing throws.
• Minor formatting adjustment in compress() signature.
