🐛 Fix import error in autometa/config/databases.py where hmmer is incorrectly imported rather than hmmscan

ctrl + f is also showing the old import in:

https://github.com/KwanLab/Autometa/blob/f372b8234766cc5e413a6c4671f78968ae682043/make_test_data.py
and

Should these also be switched?:

Autometa/tests/unit_tests/test_markers.py

Line 80 in ea91e6c

monkeypatch.setattr(hmmer, name="hmmscan", value=return_args, raising=True)

Autometa/tests/unit_tests/test_markers.py

Line 88 in ea91e6c

monkeypatch.setattr(hmmer, name="filter_markers", value=return_args, raising=True)
