`turso db inspect` should show more than just space

[glommer]

Follow up from #275, users will want to know more than their storage used. We need to show:

• bandwidth used (per day, per month, total)
• rows read (per day, per month, total)

This info should also be split on a per-location basis, so users can know which of their locations are seeing more activity than the rest

@glommer I would like to work on this. Can you assign this to me?
