FE-JS : Wallet: Support transactions to multiple recipients

[AltiMario]

Issues Fix in web-based wallet (Off-Narrative-Labs/Tuxedo#62) The current implementation of a CLI-based wallet allows sending inputs from multiple owners in a single transaction, but it only supports a single recipient for all specified outputs.

this ticket was in our proposal, can we consider it closed? (by them or us?)

Blockchain-side implementation is already inplace.No restrictions for this in BC side.
This is not implemented on the CLI-wallet side. I will implement this this week.
This can be implemented in the JS wallet without dependency on CLI-wallet.

Multiple recipients and output coins need to be linked by each recipient. Struct something like the below

struct output_per_recipients {
pub recipient: H256,,
pub output_amount: Vec,
}

#[derive(Debug, Args)]
pub struct SpendArgs {
#[arg(long, short, verbatim_doc_comment, value_parser = output_ref_from_string)]
pub input: Vec,

#[arg(long, short, verbatim_doc_comment, value_parser = h256_from_string, default_value = SHAWN_PUB_KEY)]
pub output:Vec<output_per_recipients >,

}

Current situation :
Cli-Wallet implementation is pending.
Blockchain side implementation is ready.
JS Wallet can proceed with implementation.No blocking

The frontend part is missing, but having it also means changing the workflow and interface. It is not a priority for the grant scope. It can stay in the backlog until we decide to implement it as an extra feature to show the potentiality of UTXO.

@AltiMario - This is already implemented in the wallet side.

Please see the implementation in

Implementation using Approach1 is done : Off-Narrative-Labs/Tuxedo#62 (comment)

Test result using approach1: Off-Narrative-Labs/Tuxedo#62 (comment)

Pending item is : Update the cli-wallet README file based on the approach2.

This implementation is submitted to "webservice-with-external-signing" branch.

A PR back upstream for this is welcome too if time permits :)
