Store BIP322 messages in PSBT proprietary fields and provide getter function to extract them by input index. Add `getBip322Message` function that returns the message string or null if not present. Update `addBip322Input` to persist the message alongside the BIP322 proof input. Include test coverage for single and multiple message storage, and out-of-bounds handling.
