Calculate the true blockweight payout share for a given delegate,
        assuming no exceptions were made for a voter. last_payout is a map of addresses and timestamps:
        {address: timestamp}. If no argument are given, it will start the calculation at the first forged block
        by the delegate, generate a last_payout from transaction history, and use the set_delegate info.

        If a passphrase is provided, it is only used to generate the adddress and keys, no transactions are sent.
        (Still not recommended unless you know what you are doing, version control could store your passphrase for example;
        very risky)
