Corrupted HDF5 auxfiles

The auxfiles/*.h5 seem to be corrupted. I can't open them with any of three different tools --- h5py, h5ls, and the vscode hdf5 viewer. The tools do work with other .h5 files. Git cloning again didn't help. In particular, this makes pytest fail on my laptop.

>>> h5py.File("mbhb_true.h5")
Traceback (most recent call last):
