Force-close the last state that is in the channel.db provided
If you are certain that a node is offline for good (AFTER you've tried SCB!) and a channel is still open, you can use this method to force-close your latest state that you have in your channel.db.
!!! WARNING !!! DANGER !!! WARNING !!!
If you do this and the state that you publish is not the latest state, then the remote node could punish you by taking the whole channel amount if they come online before you can sweep the funds from the time locked (144 - 2000 blocks) transaction or they have a watch tower looking out for them.
This should absolutely be the last resort and you have been warned!
