Swap `DexIncentive` with `DexPremium`, making `DexPremium` reward 'DexCurrencyId` (DRAM/MENA)

[balqaasem]

Swap DexIncentive with DexPremium, making DexPremium reward 'DexCurrencyId(DRAM/MENA). And rewarding the DexInflation into theDexPremium`

For example:

fn dex_inflation(amount: Balance) -> Self::Balance {
    let dexer_currency_id = T::DexCurrencyId::get();
    let total_issuance = T::MultiCurrency::total_issuance(dexer_currency_id),
    let max_supply = T::SerpTreasury::dexer_max_supply();
    ensure!(amount + total_issuance <= max_supply;

    T::SerpTreasury::issue_dexer(&amount);
    Ok(())
}

Better to pre-mine it and then just keep depositing through the Financial council as the Premium Incentives

Or just issue it in certain amounts (standard_inflation_rate) until it ends at MaxSupply in about 2 yrs.

The MaxSupply will be set in the SerpTreasury for only DexCurrencyId.

MaxSupply for the Currencies:

• DRAM = 1.032 Billion (1,032,000,000); (4X the InitialSupply of the DNAR);

• MENA = 10.32 Billion (10,320,000,000); (10X that of the DRAM) (4X the InitialSupply of the NEOM);

So, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ this is the updated denomination.

I suggest we distribute in a time of about 20 years... That is enough, not too small and not too large, will be more bubble-resistant.
