Allow message signing and verification

[KilianB]

The hedera sdk supports sinning and verifying message. It would be great if this feature could be exposed via hashconnect

const privateKey : PrivateKey;
const message = Buffer.from("My message to sign");
const signature = privateKey.sign(message);

const publicKey: PublicKey = privateKey.publicKey();
const isValid = publicKey.verify(message,signature);

Would love this. Is there a way to do something like this yet?

Do we have an update on this we also need this feature...
