Browse Source 
595283851 [rpc] util: add deriveaddresses method (Sjors Provoost)

Pull request description:

  Usage:

  ```sh
  bitcoin-cli deriveaddresses "wpkh([d34db33f/84h/0h/0h]xpub6DJ2dNUysrn5Vt36jH2KLBT2i1auw1tTSSomg8PhqNiUtx8QX2SvC9nrHu81fT41fvDUnhMjEzQgXnQjKEu3oaqMSzhSrHMxyyoEAmUHQbY/0/0)"
  [
    "bc1qg6ucjz7kgdedam7v5yarecy54uqw82yym06z3q"
  ] // part of the BIP32 test vector
  ```

  Avoids the need for external (BIP32) libraries to derive an address. Can be used in conjunction with `scantxoutset` as a poor mans wallet. Might be useful to test more complicated future descriptors.

  ~To keep it as simple as possible it only supports descriptors that result in a single address, so no `combo()` and ranges.~

  As discussed recently on IRC it might make sense to put this in a separate utility along with other descriptor and psbt utility functions which don't need a chain or wallet context. However I prefer to leave that to another PR.
