RPC changes
The RPC joinpsbts will shuffle the order of the inputs and outputs of the resulting joined psbt.
Previously inputs and outputs were added in the order that the PSBTs were provided which makes correlating inputs to outputs extremely easy.
The utxoupdatepsbt RPC method has been updated to take a descriptors
argument. When provided, input and output scripts and keys will be filled in
when known.
See the RPC help text for full details.
