Not passing `interp` kwargs to `DataArray.interp`

pint-xarray/pint_xarray/accessors.py

Line 754 in ca4e282

kwargs=None,

From the documentation it seems the kwargs argument is meant to be passed unmodified to xarray's DataArray.interp method. However from the line above it doesn't seem to do that.

The same goes for the assume_sorted argument by the way.

Thanks for the report, @martijnvandermarel.

This looks like a copy/paste error and is definitely not intentional (and Dataset seems to also be affected). I'd be happy to take a PR that fixes that, if you're up for it.
