LNHANCE bips and implementation

Simple unidirectional NIC (non-interactive channel) that that is immune to TXID malleability and can be natural part of pool vTXOs (virtual UTXOs) from user Alice where you have a coordinator Bob that acts as an LSP:


You would have an alternative spending branch with a 24h timelock and Alice single sig. also have a 2-of-2 musig keyspend naturally.

Alice can keep giving Bob newer more favorable distributions. Bob gates them with his single sig.

What Alice would do is give Bob a new <sigAlice> <template> pairs and the new outputs that hash to the template to move funds to Alice. outputs can include HTLCs and then their updated settlement.
