[Feature]: add support for OP_RETURN messages

[reqlez]

Describe the problem

The wallet is missing a way for users to add a message with their bitcoin transaction.

Describe the solution

Similar to Moonshine wallet that has the feature, I propose adding an OP_RETURN message field in string format that converts it to HEX automatically for the users.

Moonshine is now not working with latest Android phones, so a replacement would be useful and would set the wallet apart from others, that do not have the feature.

Additional context

Another great feature, would be to add QR code scanning for the new OP_RETURN field.

Thanks for the feature request!

For future reference, Bitkit is capable of creating OP_RETURN messages here, it's just not exposed in the current UI when creating a transaction. We would have to create an additional text field that modifies the message value in the transaction object.

One more thing i wanted to note, in Moonshine, when you exit app to copy paste BTC address, then come back from another app to copy paste into the "message" field, the BTC address resets. Would be nice for the fields not to reset every time you open Bitkit while you are on the send tx screen, whenever you guys get the OP_RETURN implemented in UI, this is another tip :) I guess another way is to have a button "include message" and then you click next and input message into another screen with BTC address and amount already saved from previous step.

Hello, could we follow up on this?

We'd really love to use Bitkit as the premiere wallet for our dapp. Thanks.
