Need more disk I/O friendly shear catalog format

Pairs are sometimes not saved in output during xshear_metacal.py

Previous implementation was not config independent, new version have to be generated procedurally

Add functionality to calculate shape noise-only covariance from random rotations of said source catalog

Add mass maps with rotation to stack along arbitrary sky direction

1. python rotate_shear.py --wconfig crashes with error:
   main_xconfig_fname = paths.fullpaths["xconfig"]
   KeyError: 'xconfig'

2. python rotate_shear.py crashes at:
   with open(paths.fullpaths['flist']) as file:
   flist = file.read().splitlines()

Add functionality to handle multiple source bins
