inspiral_extrinsics.py: creating new p_of_instruments files will fail due to python2 and 3 incompatibility
String decoding is not needed for h5py anymore in python3: https://git.ligo.org/lscsoft/gstlal/-/blob/master/gstlal-inspiral/python/stats/inspiral_extrinsics.py#L1895
but the files previously generated via python2 are here and require it:
If new p_of_instruments files are made, then attempting to run the above from_hdf5 method will fail because it separately reads in python2 and python3 files. This can be avoided with a try except to catch python2 vs python3 generated files.
