astropy units

[jrob93]

How do we want to handle parameters that are of type "Quantity". I.e. objects that have a value and unit property https://docs.astropy.org/en/stable/units/

So far I have tried to write the PhaseCurve class such that it can handle model parameters with/without units. This is becasue sbpy expects units by default. As long as it doesn't make things tricky I would lean towards trying to use code in adler that is agnostic to variables with/without units. That being said, we will have to strip units from variables at some point anyway, in order to write values to a database.

So the datacalasses I wrote don't care whether they're getting a Quantity or a float. It's just write-out that's problematic. I think the easiest way to handle this is to strip units before writing to a database - can also add a check to validate that the units are correct before they're removed.
