additional_param_names

[caseylam]

Parametrization Class Family: additional_param_names doesn't have all the self.<blah> quantities we define in __init__. It only has a subset.

Can we add those all in? That way we can access all the posteriors in the table.

We could calculate it from the available posteriors, but kind of annoying.

Follow up on this: we need to figure out how to make our parameterizations easier to use/self-consistent so you can get all parameters, no matter which parameterization you use)

e.g. if you fit in bsff and mag_src, you should be able to get out a posterior for mag_base.
