Issue DM-4162: Please implement a warper that works with a single XYTransform
At present we only warp images based on a pair of {{Wcs}}. This is needlessly restrictive. We should be able to define the transformation by function that computes {{f(x,y) -> x',y'}}, e.g. an {{XYTransform}}. Note that reversibility, while not strictly necessary, is very desirable. Hence we might as well use {{XYTransform}}. I suggest we have only one underlying implementation in order to avoid code duplication. This could easily be done by implementing an {{XYTransform}} that combines a pair of WCS.
