Revault transactions

Typesafe routines to create Revault-specific Bitcoin transactions.

We use PSBTs as defined in bip-0174 for data structure as well as roles distribution.

Structs

CancelTransaction	The transaction “revaulting” a spend attempt, i.e. spending the unvaulting transaction back to a deposit txo.
DepositTransaction	The funding transaction, we don’t create nor sign it.
EmergencyTransaction	The transaction spending a deposit output to The Emergency Script.
FeeBumpTransaction	The fee-bumping transaction, we don’t create nor sign it.
SpendTransaction	The transaction spending the unvaulting transaction, paying to one or multiple externally-controlled addresses, and possibly to a new deposit txo for the change.
UnvaultEmergencyTransaction	The transaction spending an unvault output to The Emergency Script.
UnvaultTransaction	The unvaulting transaction, spending a deposit and being eventually spent by a spend transaction (if not revaulted).

DUST_LIMIT	We refuse to create a stakeholder-pre-signed transaction that would create an output worth less than this amount of sats. This is worth 30€ for 15k€/btc.
INSANE_FEES	We can’t safely error for insane fees on revaulting transactions, but we can for the unvault and the spend. This is 0.2BTC, or 3k€ currently.
REVAULTING_TX_FEERATE	The feerate, in sat / W, to create the revaulting transactions (both emergency and the cancel) with.
TX_VERSION	This enables CSV and is easier to apply to all transactions anyways.
UNVAULT_CPFP_VALUE	The value of the CPFP output in the Unvault transaction. See https://github.com/revault/practical-revault/blob/master/transactions.md#unvault_tx
UNVAULT_TX_FEERATE	The feerate, in sat / W, to create the unvaulting transactions with.

A Revault transaction.

spend_tx_from_deposits	Get a spend transaction out of a list of deposits and derivation indexes. The `unvault_descriptor` will be derived for each and should not be beforehand.
transaction_chain	Get the entire chain of pre-signed transaction out of a deposit. No feebump input.
transaction_chain_manager	Get the chain of pre-signed transaction out of a deposit available for a manager. No feebump input.
