py-importlib-metadata: updated to 1.6.1

v1.6.1
Added Distribution._local() as a provisional demonstration of how to load \ 
metadata for a local package. Implicitly requires that pep517 is installed.
Ensure inputs to FastPath are Unicode.
Tests now rely on importlib.resources.files (and backport) instead of the older \ 
path function.
Support any iterable from find_distributions.
