Closes #2847
Following the proposal in #8005 (comment), this PR adds encoding/decoding machinery for
pd.IntervalArrayobjects. I use an ad-hoc convention:__xarray_bounds__. This is not configurable at the moment."closed", and"dtype"(this is always"pandas_interval").It is possible to create an IntervalArray with Datetime and Timedelta objects so I've stuck the IntervalCoder first in the encoding pipeline, and last in the decoding pipeline. That way it stays independent.
