error in Finding_Coincident_Airborne_and_Orbital_Data notebook on latest xarray

[itcarroll]

To reproduce, launch a binder with the latest earthaccess, and try the following in a console.

import earthaccess

aviris_collection_query = earthaccess.collection_query().keyword('AVIRIS-3')
aviris_collection_query.fields(['Shortname', 'EntryTitle','Version']).get()

This may just be a query style that pre-dates earthaccess.search_datasets or it may mean to do something nifty that I haven't realized.
Either way, it raises a serialization error.

Thanks for pointing this out, it was just an older query style that we've just been copying. Going to add some earthaccess.search_datasets cells to replace. This is present in few notebooks:

• python/Finding_Coincident_Airborne_and_Orbital_Data.ipynb
• python/emit_neon/01_Finding_Co-located_NEON_EMIT_Data_NIWO.ipynb
• python/emit_ecostress/01_Finding_Concurrent_Data.ipynb

Sorry for the title slop ... of course I meant latest earthaccess not xarray 😵‍💫!
