Algos

Insert an address

send wallet an address that we KNOW is in the wallet
include the address's index

Scan addresses. (map xpub (pair list list)) outgoing wire is /scan/xpub/change/index

keep list of whether we've heard back on an address (list (unit used))
every time we get a response
- insert the address into the wallet if it's used
- check whether (lent (murn l)) == max-gap
- if it does, run lien--if any used, continue
- if none used, the wallet is scanned.
