[Explore]: Python-based solutions for unstructured to structured regridding

Is your feature request related to a problem?

As discussed in today's meeting (06/05/24):

The last remaining item is exploring a solution for regridding unstructured grids to structured. Currently, there seems to be no Python based tool that does that to the best of our knowledge. Other non-Python tools that are commonly used include nco/(ncremap) and TempestRemap.

We reached the following pathway:

1. Reach out to UXarray development team to get a possible timeline for this feature (UXarray discussions post)
2. Reach out to Paul Ullrich to check UXarray roadmap
3. Reach out to Paul Ullrich to explore TempestRemap in conjunction with Steve's KDTree regridding algorithm, and if there are any Python-based tools for unstructured to structured regridding

• Can we port over portions of TempestRemap to Python/Cython?
