Is your feature request related to a problem or challenge?

I am trying to add support for Generated Columns in Delta-rs. For this to be functional, we need the spaceship operator to be implemented in datafusion SQL. Currently it's not supported as we can see here:

DeltaError: Generic DeltaTable error: This feature is not implemented: Unsupported SQL binary operator Spaceship

Describe the solution you'd like

Add support for parsing <=> if it exists in a sql statement.

Describe alternatives you've considered
