> 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.
