Description

Python 3.9 removed a couple of deprecated functions/arguments that we
used, which was the only thing preventing us from claiming Python 3.9
support.

This change updates our usage of json.loads() to not pass an
encoding= argument (removed in Python 3.9) and to instead handle
decoding byte strings up-front, and to update unit tests to not depend
on an internal, deprecated method on HTMLParser.

setup.py has been updated to reflect the current supported list of
Python versions.

Testing Done

Unit tests pass.

Is this really something that can happen? It seems like if we had double-encoded JSON, once it's in unicode, loadsing it should stay in unicode.

Probably. I was just keeping the same logic. I'll change it.

Change Summary:

Removed a probably-unnecessary second pass of the handling of encodings when JSON deserialization results in a string.
