Make transaction rejection error (node) same as blockfrost submit error

[vladimirvolek]

Requires:

• Decode node submit error CBOR #44
• Verify our Rust CBOR error deserializer against Haskell's serializer #42

Current situation

blockfrost-platform/src/node.rs

Lines 57 to 58 in 946d918

	let reason_hex = hex::encode(&reason.0);
	warn!("Transaction was rejected: {}", reason_hex);

Is this about mimicking errors documented in https://docs.blockfrost.io/#tag/cardano--transactions/POST/tx/submit ?
If so, giving me access to the proxy code might greatly help. @vladimirvolek

Also, the endpoint https://cardano-mainnet.blockfrost.io/api/v0/tx/submit returns only a plain error message string, without a status_code, error, or details field.
