Unreleased version of xarray (0.18) breaks things

[snowman2]

https://github.com/corteva/rioxarray/runs/1990677174?check_suite_focus=true

test_to_raster fails with:

AttributeError: 'DataArray' object has no attribute 'values'

test_to_raster__dataset__mask_and_scale fails with:

IndexError: too many indices

Possibly related: pydata/xarray#4934

I can report a similar error, although xarray is functioning without issue.

AttributeError: cannot set attribute '_file_obj' on a 'DataArray' object. Use __setitem__ styleassignment (e.g., `ds['name'] = ...`) instead of assigning variables.

xarray==0.17.0
rioxarray==0.3.0

#254 is what you are experiencing. This has been addressed in the 0.3.1 release.

Can confirm, thanks @snowman2

@snowman2 another breakage come from the rename of LazilyOuterIndexedArray to LazilyIndexedArray un master pydata/xarray#5111

Note that I already proposed a PR to keep the old name around to ease the migration: pydata/xarray#5112

@alexamici, thanks for your help getting things working again 👍
