Go through all the addresses that could have funds of channels that were force-closed by the remote party. A public block explorer is queried for each address and if any balance is found, all funds are swept to a given address
### Synopsis
This command helps users sweep funds that are in
outputs of channels that were force-closed by the remote party. This command
only needs to be used if no channel.backup file is available. By manually
contacting the remote peers and asking them to force-close the channels, the
funds can be swept after the force-close transaction was confirmed.
--walletdb string read the seed/master root key to use fro sweeping the wallet from an lnd wallet.db file instead of asking for a seed or providing the --rootkey flag
