Wallet rescan from a given height rather than from beginning

[scalahub]

It will be preferable if we can ask the node to rescan blockchain and the wallet from some given height instead of from the beginning.
Many dApps rely on recently issued transactions so it is often wasteful to rescan the entire blockchain

Oracle-core would very much appreciate this feature implemented. It'd minimize pool downtime on update significantly. See ergoplatform/oracle-core#242 for details.

It is implemented long time ago, anything needed?

Oh, right. My bad. I forgot that this feature exists. We even used it initially but we had to disable it because the wallet does not see anything below the given height, including the user's coins. Is it intended to work this way?

well, yes, no efficient way to find what was before beginning of a scan without scanning
