Fix two issues with test suites
This PR updates the parse-conda-requirements.py
script to use pkg_resources
to parse requirements files, rather than the internal API from pip
, which breaks every now and then.
ADDENDUM: this also fixes a failing StateVector
test by correcting a dataset version reference which was incorrect (prior to gwosc-0.5.3 that client didn't actually return the right dataset, so we didn't notice that ours was wrong).
