Add support for creating OP_RETURN outputs in PSETs using the
'data:<hex>' address format.
Example usage:
{"address": "data:534149440101...", "asset": "...", "amount": 0}
This is useful for embedding arbitrary data in Liquid transactions,
such as protocol identifiers (e.g., SAID Protocol) or other metadata.
The hex data following 'data:' is decoded and pushed after OP_RETURN
in the script pubkey.

Summary
Add support for creating OP_RETURN outputs in PSETs using the
data:<hex>address format.Motivation
When working with Simplicity transactions on Liquid, there are use cases where you need to embed arbitrary data in a transaction output, such as:
Currently,
simplicity pset createonly supports regular addresses and the specialfeekeyword. This PR adds support for OP_RETURN outputs.Usage
To create an OP_RETURN output, use the
data:prefix followed by hex-encoded data:{ "address": "data:534149440101deadbeef", "asset": "6f0279e9ed041c3d710a9f57d0c02928416460c4b722ae3457a11eec381c526d", "amount": 0 }This will create a transaction output with the script:
Implementation

Tested on Liquid Testnet for creating transactions with embedded SAID Protocol identifiers.
