make xee compatible with rioxarray

[12rambau]

when dealing with rasters represented as xarray datasets, rioxarray have proven to be extremely useful to perform all sort of enoying tasks like reproject, window reading, parralalesiation, plottting etc... It shine with a vibrant community and I don't see any reason to reinvent the wheel here.

As rioxarray is a xarray extention, it's automatically loaded upon import. The only limitation to use it is to make sure that datasets generated by xee have all the metadata required by GDAL and rio to perform their magic.

Do you think it would make sense ? Happy to propose a PR in this direction.
