No longer works with python 3.10

[kmccurley]

This is essentially abandonware. It has a dependency upon collections.Iterable, which was removed in python 3.10.

In biblib/bib.py, changing the third import to

import collections.abc

and line 97 to read

elif isinstance(str_or_fp_or_iter, collections.abc.Iterable) and 

appears to fix (tested on python 3.11)
