Kaspawallet - Force "send transaction" from specific address

[thesheepcat]

Currently, kaspawallet does not allow users to spend specific funds on a specific address when creating a transaction.

I suggest to add the possibility to force a specific address when sending funds.

Example command: ./kaspawallet send -t RECEIVING_ADDRESS -a FROM_ADDRESS -v AMOUNT

In case the address does not have enough funds, an error is generated.

Eventually, in the future, multiple addresses can be passed as parameter and the wallet knows which addresses can take the coins from.
