cryodrgn_utils filter_star missing optics table RELION 3.1

[ryanfeathers]

cryodrgn_utils filter_star does not return an optics table when run on RELION 3.1 format star files.

Expected output: A star file containing data_optics and data_particles blocks

This functionality has been added in v3.3.3-rc1, with the new optics table only having the optics groups present in the new filtered dataset:

Furthermore, in the case of output into separate micrograph files using -m, each file's optics table only contains the optics groups present for the corresponding micrograph:
