This changes the resampling algorithm to use the default for interpolating the GACOS product to the ARIA crop. It also removes some unnecessary masking. After these changes, we agree within numerical precision to the GACOS correction written with MintPy (note I had to do some internal hacking to output a single SLC date and inverted units to compare with MintPy from aria tools)

Units are in meters.

@sssangha the unit test seems to fail. This might be more related to something else that you are fixing on your end.
