This PR updates DiffstarPop to the final model used in the paper, which uses the sigslope model for the scaling relations of the mean ecrit and qtime parameters.

The main files updated are the sfh_pdf_mgash.py kernel file, and the best fit diffstar and diffstarpop fits parameter files. The DEFAULT_DIFFSTARPOP_PARAMS are taken from sfh_pdf_mgash.py, which match the best-fit diffstarpop params of UniverseMachine (no merging).

How does this PR relate to #105?

It's the same, but cleaner. #105 has a couple of model variations, called ecrit and ecrit_qt. This PR directly updates the default diffstarpop files, i.e.diffstar/diffstarpop/kernels/sfh_pdf_mgash.py, and updates all the diffstarfits and diffstarpopfits params files, to the final model that is used in the paper.

So we can close #105.
