Changed the interface to wcs_from_points to better match the similar function in astropy, and added the fitting of the inverse transform.
After discussion with @nden, we decided to not allow a WCS to be passed in to be refit (as is done in astropy - 'projection' can be a projection code or a WCS). Additionally, in astropy a string projection code is supplied but here a projection type is used.
