Current coveragepy-lcov is incompatible with newly released coverage 7.0.0

The stack trace says most of it when installed with coverage 7.0.0:

Traceback (most recent call last):

ImportError: cannot import name 'FnmatchMatcher' from 'coverage.files' (c:\hostedtoolcache\windows\python\3.8.10\x64\lib\site-packages\coverage\files.py)

It seems that FnmatchMatcher has been replaced with GlobMatcher. If I'm not mistaken, it looks like it's a straight-up rename (but fixing this could unmask other issues with 7.0.0 - I have not confirmed).
