ENH: Filter by font when removing text

[samuelbradshaw]

This is related to a discussion from a couple of months ago: #3049.

The change adds an optional font_names attribute to PdfWriter.removeText(), allowing users to remove all text with a certain font from the PDF. Example:

from pypdf import PdfWriter

pdf_path = '/path/to/file.pdf'

writer = PdfWriter(clone_from = pdf_path)
writer.remove_text(font_names = ['Helvetica-Bold'])
writer.write(pdf_path)
