Missing import in bilby.gw.detector.load_data_from_cache_file

bilby.gw.detector.load_data_from_cache_file fails since it appears to be missing an import lal:

python bilby_run.py

The line mentioned in the traceback is here: https://git.ligo.org/lscsoft/bilby/-/blob/f8b004a80fa2f735b171b144154d5563f569abdf/bilby/gw/detector/init.py#L254

Sure enough, that file does not import lal, so I believe adding it would fix this issue.
