Change MultiSig Required Signatures

Changes the required number of signatures on a multisig wallet. The required number of signatures is the minimum number of additional signatures for any transaction performed on a multisig wallet before the transaction is executed.
Note: The required number of signatures cannot be increased to such a value that would make the wallet unusuable. (More required signatures than allowed signers.
Note: Any combination of allowed signatures will enable the transaction, as long as the number of required signatures is reached.

Method: `changemultisigs`

Input parameters:
