In-state ship-from addresses for remote seller licenses

No more monthly manual adjustments, and less room for human error.

Some sellers hold a remote seller license in a state but still ship from inside that state from time to time. Those in-state transactions do not fit the registration type, and they used to require manual adjustment every month to comply.

Zamp's tax engine now handles these transactions automatically, applying the treatment that matches the seller's registration.
