When the\ndeadline is approaching, the fee function will increase the fee rate and\nperform an RBF.\n\nWhen a force close happens, all the outputs from the force closing\ntransaction will be registered in the sweeper. The sweeper will then handle\nthe creation, publish, and fee bumping of the sweeping transactions.\nEverytime a new block comes in, unless the sweeping transaction is\nconfirmed, an RBF is attempted. To interfere with this automatic process,\nusers can use BumpFee to specify customized fee rate, budget, deadline, and\nwhether the sweep should happen immediately. It's recommended to call\n`ListSweeps` to understand the shape of the existing sweeping transaction\nfirst - depending on the number of inputs in this transaction, the RBF\nrequirements can be quite different.\n\nThis RPC also serves useful when wanting to perform a Child-Pays-For-Parent\n(CPFP), where the child transaction pays for its parent's fee.

This HTLC output isn't\ndirectly on our commitment transaction, but is the result of confirmed\nsecond-level HTLC transaction. As a result, we can only spend this after\na CSV delay and CLTV locktime as part of the script enforced lease\ncommitment type.\n - TAPROOT_PUB_KEY_SPEND: A witness type that allows us to spend a regular p2tr output that's sent\nto an output which is under complete control of the backing wallet.\n - TAPROOT_LOCAL_COMMIT_SPEND: A witness type that allows us to spend our settled local commitment after a\nCSV delay when we force close the channel.\n - TAPROOT_REMOTE_COMMIT_SPEND: A witness type that allows us to spend our settled local commitment after\na CSV delay when the remote party has force closed the channel.\n - TAPROOT_ANCHOR_SWEEP_SPEND: A witness type that we'll use for spending our own anchor output.\n - TAPROOT_HTLC_OFFERED_TIMEOUT_SECOND_LEVEL: A witness that allows us to timeout an HTLC we offered to the remote party\non our commitment transaction. We use this when we need to go on chain to\ntime out an HTLC.\n - TAPROOT_HTLC_ACCEPTED_SUCCESS_SECOND_LEVEL: A witness type that allows us to sweep an HTLC we accepted on our commitment\ntransaction after we go to the second level on chain.\n - TAPROOT_HTLC_SECOND_LEVEL_REVOKE: A witness that allows us to sweep an HTLC on the revoked transaction of the\nremote party that goes to the second level.\n - TAPROOT_HTLC_ACCEPTED_REVOKE: A witness that allows us to sweep an HTLC sent to us by the remote party\nin the event that they broadcast a revoked state.\n - TAPROOT_HTLC_OFFERED_REVOKE: A witness that allows us to sweep an HTLC we offered to the remote party if\nthey broadcast a revoked commitment.\n - TAPROOT_HTLC_OFFERED_REMOTE_TIMEOUT: A witness that allows us to sweep an HTLC we offered to the remote party\nthat lies on the commitment transaction for the remote party. We can spend\nthis output after the absolute CLTV timeout of the HTLC as passed.\n - TAPROOT_HTLC_LOCAL_OFFERED_TIMEOUT: A witness type that allows us to sign the second level HTLC timeout\ntransaction when spending from an HTLC residing on our local commitment\ntransaction.\nThis is used by the sweeper to re-sign inputs if it needs to aggregate\nseveral second level HTLCs.\n - TAPROOT_HTLC_ACCEPTED_REMOTE_SUCCESS: A witness that allows us to sweep an HTLC that was offered to us by the\nremote party for a taproot channels. We use this witness in the case that\nthe remote party goes to chain, and we know the pre-image to the HTLC. We\ncan sweep this without any additional timeout.\n - TAPROOT_HTLC_ACCEPTED_LOCAL_SUCCESS: A witness type that allows us to sweep the HTLC offered to us on our local\ncommitment transaction. We'll use this when we need to go on chain to sweep\nthe HTLC.
