Testing and Updating Examples (#837)

* updated viewshed gpu example

* updated classification notebook with more reliable data source and rioxarray loading

* bunch of notebook updates

* ran and cleared example noe notebooks

* The sentienl cloudless mosaic notebook will removed because it relies on an external service and only uses the true_color function from xarray-spatial, so its generally unfocused and won't be maintained.

* tested and cleared all notebooks
