Improve constrainedPolyModel to use constrained affine chip and unconstrained polynomial visit models

    Details

      Description

      Now that the constrainedPolyModel is selectable, we should improve it to bring it closer in line with what we expect the LSST Frames model will be. This would entail switching the TwoTransfoMapping to have T1 be an affine gtransfo constrained per chip (chips don't wiggle much), and T2 be an unconstrained polynomial (to nominally take out the variable sky component plus the optics, which we'll constrain later).

      This may be as simple as swapping the models and where the constraint is defined. It would be very useful to have better plotting tools available to inspect the resulting models, and also possibly to have AST persistence available so we aren't having to squash the result into a TAN-SIP.
