Removes nbodykit dependencies in all usages throughout the pipeline. Specifically,
[ ] cmass.bias.apply_hod and relevant dependencies have been switched to using halotools, which nbodykit was using on the backend anyway
[ ] Cosmological conversions (ra/dec/z <-> comoving positions) have been replaced with astropy tools, which nbodykit was also using
[ ] The main functions in calc_Pk_nbkit was renamed to calc_Pk and its contents were totally rewritten to use pypower, which itself was written to mimic the nbodykit FKP implementation.
[ ] nbodykit's installation was removed from requirements.txt, setup.cfg, and documentation
[ ] General documentation/organization was cleaned up slightly
