@huikyole Looks like your changes don't work for 2D latlon arrays, as per
CI build logs:
```
======================================================================
ERROR: test_two_dimensional_lats_lons
(ocw.tests.test_dataset_processor.TestSpatialRegrid)
----------------------------------------------------------------------
Traceback (most recent call last):

new_values_temp = griddata((lons[mask_index], lats[mask_index]),
values_original[mask_index],
IndexError: index 2 is out of bounds for axis 0 with size 2
```
Given that regridding is probably one of the largest bottlenecks in our
RCMES workflows, I think it is also worth profiling both this version (once the
above error is fixed) and the old map_coordinates version to see if there are
any performance impacts, since the spatial_regridding tests seem to be running
more slowly.
