Description

As it says in the title, I think this would be a very handy attribute to have available in Python. You can get it by converting to pandas and using `DataFrame.nbytes` but this is wasteful of both time and memory so it would be good to have this information on the `pyarrow.Table` object itself.

This could be implemented using the _sizeof_ protocol
