Notes to the reviewers

Step to review this include making a payjoin transaction

Run a receiver to get a BIP21 URI then pass it to the sender as seen in docs

bdk-cli/README.md

	To start a Payjoin session as the receiver with regtest RPC and example OHTTP relays:
	```
	cargo run --features rpc -- --network regtest wallet --wallet payjoin_wallet1 config --ext-descriptor "wpkh(tprv8ZgxMBicQKsPd2PoUEcGNDHPZmVWgtPYERAwMG6qHheX6LN4oaazp3qZU7mykiaAZga1ZB2SJJR6Mriyq8MocMs7QTe7toaabSwTWu5fRFz/84h/1h/0h/0/*)#8guqp7rn" --client-type rpc --database-type sqlite --url "127.0.0.1:18443"
	cargo run --features rpc -- wallet --wallet payjoin_wallet1 sync
	cargo run --features rpc -- wallet --wallet payjoin_wallet1 balance
	cargo run --features rpc -- wallet --wallet payjoin_wallet1 receive_payjoin --amount 400000 --max_fee_rate 1000 --directory "https://payjo.in" --ohttp_relay "https://pj.bobspacebkk.com" --ohttp_relay "https://pj.benalleng.com"
	```
	To send a Payjoin with regtest RPC and example OHTTP relays:
	```
	cargo run --features rpc -- --network regtest wallet --wallet payjoin_wallet2 config --ext-descriptor "wpkh(tprv8ZgxMBicQKsPfBxswkATvZRQ9kDdRbJPtHYZaZCARL2myxcK7DqsqPhRo2G2rRVHFPbowq63BE6S4k2pUMYeF2fUMTT63Q7zhoXtKsM1FaS/84'/1'/0'/0/*)#qf5gnqrf" --client-type rpc --database-type sqlite --url "127.0.0.1:18443"
	cargo run --features rpc -- wallet --wallet payjoin_wallet2 sync
	cargo run --features rpc -- wallet --wallet payjoin_wallet2 balance
	cargo run --features rpc -- wallet --wallet payjoin_wallet2 send_payjoin --ohttp_relay "https://pj.bobspacebkk.com" --ohttp_relay "https://pj.benalleng.com" --fee_rate 1 --uri "<URI>"
	```

To test resumption, interrupt either side with Ctrl+C mid-session then run resume on that side to continue. A few scenarios worth covering: receiver resuming after interrupt and sender resuming after interrupt. Use history after each scenario to confirm the session state was persisted correctly.
