• [x] remove pins and create new lock file. Add arm-x64 for OSX. Tested on Apple M1 Pro.
• [x] replace deprecated xarray.open_rasterio with rioxarray.open_rasterio
• [x] pin tornado. I've been having rendering issues on OSX and seeing the following zmq error on OSX

I've been experiencing rendering issues, along with a JS syntax error. As per this [jupyterhub discourse](https://discourse.jupyter.org/t/jupyter-notebook-zmq-message-arrived-on-closed-channel-error/17869/2) with similar error, the proposed solution of pinning tornado server seems to be consistently working correctly. The error I see (see below) points to the asyncio event loop so pinning tornado to older version does seem to point in the right direction.

I accidentally branched off the work I was doing on the landuse classification project. I'll close this and submit new PR only for this example.
