py-coverage: updated to 5.1

Version 5.1:
The JSON report now includes counts of covered and missing branches.
On Python 3.8, try-finally-return reported wrong branch coverage with decorated \ 
async functions (issue 964). This is now fixed.
The :meth:`~coverage.Coverage.get_option` and \ 
:meth:`~coverage.Coverage.set_option` methods can now manipulate the [paths] \ 
configuration setting.
