/**
 * ShutdownMessage represents the `shutdown` message defined in BOLT #2 of the Lightning
 * Specification. This message can be sent by either node. The scriptPubKey must be a valid P2WPKH,
 * P2WSH, P2SH-P2WPKH, P2SH-P2WSH, or any valid witness script if option_shutdown_anysegwit is
 * negotiated and it should be same as `shutdown_scriptpubkey` value if it was sent during
 * `'open/accept' channel message`. Therefore, if both conditions hold true resulting transaction
 * will propagate to miners. If shutdown is sent by either node, corresponding node should send
 * commitment_signed to commit any outstanding changes before replying shutdown. Once shutdown is
 * sent by both nodes no new HTLCs should be added or accepted by the channel. After successful
 * handshake of shutdown message, fee negotiation and signature sending can begin with
 * `closing_signed` message.
