Reinstate libpython3.X.so to support embedded python in liblalsimulation

In order to support calling Python waveform generates from the LALSimulation C code, liblalsimulation needs to link against libpython3.X.so. However, that library is not in the pypa/manylinux images that are used to build the Linux wheels for LALSuite.

Are we able to 'reinstate' libpython3.X.so to support linking?

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
