Review comment:
That's an interesting idea! In my use case, the TableProvider impl
interprets the filters synchronously after _asynchronously_ preparing the
necessary data externally from DataFusion, but yeah, I could see that happening
too.
If we didn't make this change, I suppose implementations could still use
these filters within the returned `ExecutionPlan`'s `execute` method for now to
enable async use cases?
