witnessClaimHtlcTimeoutFromCommitTx

fun witnessClaimHtlcTimeoutFromCommitTx(localSig: ByteVector64, htlcReceivedScript: ByteVector): ScriptWitness

If remote publishes its commit tx where there was a local->remote htlc, then local uses this script to claim its funds after timeout (consumes htlcReceived script from commit tx)
