Ability to print MuPDF errors to logging instead of stdout

[jamesbraza]

Is your feature request related to a problem? Please describe.

PyMuPDF==1.24.10 will occasionally print MuPDF errors to stdout.

The issue with print is:

• Random stdout prints mess with CLI utilities like rich.Progress bars
• Misses the opportunity for the benefits of Python logging (process global message formatting and/or filtering)

Describe the solution you'd like

Either:

• PyMuPDF to expose a way for callers to "install" a logging.Logger instead of print
  • And message to support a "level" argument (e.g. error level, debug level, etc)
• PyMuPDF to move to Python logging

Describe alternatives you've considered

None

Additional context

None

Latest PyMuPDF in git has new function pymupdf.use_python_logging() that allows PyMuPDF messages to be sent to Python's logging module. See: https://github.com/pymupdf/PyMuPDF/blob/main/src/__init__.py#L109

The function docstring describes how to use it, but we'll also add it to the main documentation soon.
