Regsister fsspec interface with fsspec

The following stackoverflow question brought to my attention that, although this repo has an fsspec-compatible class, it is not registered with fsspec, so calls like fsspec.open("gdrive://...") don't work. Even importing the library does not seem to do the registration. (They DO work with the older gdrivefs.)

We should figure out what the appropriate protocol to use is and make sure that users have as smooth a path as possible to loading data off gdrive via fsspec.

Inizia individuando la classe compatibile con fsspec esistente e verificando come vengono registrati i protocolli fsspec. Conferma il protocollo appropriato per Google Drive e verifica che l'importazione di PyDrive2 consenta a fsspec.open("gdrive://...") di caricare correttamente i dati, includendo un test di regressione se la struttura dei test del repository lo supporta.

Scritto dal modello di indicizzazione a partire dal testo della issue.
