Add a `lookahead` for addresses #20

Closed theanmolsharma closed 4 months ago

Generate and save 10 addresses on wallet initialization
When generating a new address at index i, return address at index i from db. Generate and save the address at index i + 10
This feature will require the following updates to wallet-db:
- Add a key P to src/wallet/db/level/layout.ts
- Update saveAddress() to store path (key) and address (value)
- Rename getAddress() to getPathFromAddress()
- Add a new function getAddressFromPath()

Does this mean we store address:path in wdb.A and path:address in wdb.P. Isnt this data duplication and if one of these is most commonly used can we just store that and if needed iterate over all db entries to get the other one?
