Should split_job_s2grid and split_job_hex return original geometry instead of Points?

[VincentVerelst]

Currently both job splitters use the centroid of the geometry to determine which tile/hex they belong to. However, after the geometries are split per tile/hex, they aren't converted back to the original geometry, but instead kept as Points.
Would it be useful to return the original geometries instead of their centroids after the job splitting?

I think by default the original polygons should be returned, but we could provide an argument to use the centrods instead
