Attempt to construct a RampModel from a DataModel

If the model has a resultantdq attribute, this is copied into the RampModel.groupdq attribute.

Otherwise, this conversion does not do a detailed mapping between all of the new and old metadata, but instead opportunistically looks for fields with common names and assigns them. Other metadata with non-matching names is simply copied in place. This allows processing to proceed and preserves the original metadata, but the resulting files have duplicates of many entries.

Parameters:: model (FpsModel, RampModel, ScienceRawModel, TvacModel) – The input data model (a RampModel will also work).
Returns:: ramp_model – The RampModel built from the input model. If the input is already a RampModel, it is simply returned.
Return type:: RampModel
