Add options to filter streams by tags.
Description of the Change
This branch adds options to subunit-filter to have it filter by tags. It has three main components:
1. Separating out a _PredicateFilter from TestResultFilter.
This simplifies TestResultFilter, leaving it managing two concerns: assembling options into a predicate and transforming results. It will be much easier to separate out the 'transforming results' concern after this change.
It is likely that _PredicateFilter could also be written in terms of TestByTestResult at some point.
2. Extending the predicate function to take 'tags'.
I've tried to do this in a way that preserves backwards compatibility and allows any users of TestResultFilter who've had a predicate function that does not support tags to continue using their code unchanged. Perhaps this is not needed.
3. Cleaning up subunit-filter
It behaves a little differently to the other filter commands, and has a different set of options, but these cleanups share code where we can and make the differences -- I hope -- more obvious.
None of this works without the fixes to TagCollapsingDe
