Granular, per-pixel statistics method.

[delucchi-cmu]

See astronomy-commons/lsdb#550

Adds a method in HATS to get granular per-pixel statistics. This is really customizable, to reduce the size of the returned object in case there are many pixels or many columns (or both).

Extracts some shared logic with the similar aggregate_column_statistics method.
