> This will simply sum up all of the buffers. It will overestimate in a few
> cases:
> * If there are offsets it will overestimate
> * If there are shared buffers it will overestimate
> It only measures the size of the buffers and will not consider the control
> data (e.g. the C objects wrapping the data) or, specifically for ExecBatch,
> it will not count scalars.
