Question: Cashout limit limits

[bedeho]

We have limits on the limits the lead can set, so spefically

    pub const MinimumCashoutAllowedLimit
    pub const MaximumCashoutAllowedLimit

constrain what lead can do in update_channel_payouts to update the actual limts in storage

        pub MaxCashoutAllowed get(fn max_cashout_allowed) config(): BalanceOf<T>;
        pub MinCashoutAllowed get(fn min_cashout_allowed) config(): BalanceOf<T>;

do we really need this? This was perhaps even an audit finding, not sure :D
