[wip] Remove pyfastx build/runtime dependencies

The next version of Augur (to be released) will support versions of
pyfastx that provide wheels for Python 3.10.

After the release, run CI on this commit and see if it works. Not sure
if the pyfastx wheel includes the runtime dependencies. Maybe separate
installation is still necessary?
