Refactor QPDF::parse_xrefEntry

Move reading of the entry from read_xrefTable to parse_xrefEntry.
Split parse_xrefEntry into two new methods read_xrefEntry and
read_bad_xrefEntry. read_xrefEntry is optimised for reading
correct entries. To handle incorrect entries it calls read_bad_xrefEntry,
which is largely unchanged from parse_xrefEntry.

This triggers compilation failures with certain C++20 compiler configurations.
