fun recoverUnspent(wallet: Wallet, numAddrToSearch: Int, numAccountToSearch: Int = 1, startAddrIndex: Int = 0, startAccountIndex: Int = 0): List<Spendable>
Search a variety of derivation paths for unspent utxos and add them into this wallet if discovered. These utxos are not swept, so may be forgotten if you recreate this wallet from a recovery key.
