Auto rechunk to enable blockwise reduction #380

Open dcherian opened 3 months ago

dcherian commented 3 months ago

Done when

  1. method is None
  2. Grouping and reducing by a 1D array
  3. by is sorted.

We gate this on fractional change in number of chunks and change in size of largest chunk.

Closes #359
