fix: support for calculating fees for statemint, and statemine and their test nets.

[TarikGul]

Update the calc package to support the Multiplier for statemint and statemine and their testnets. Update the configs and separate statemint from statmine. Everything has been tested locally with the calc package.

After this PR is merged, it should be followed up by a PR to release and update the calc package.

Did you consider swapping around the logic a bit here; just check for the weird cases and give every one else new_i128 by default?

[TarikGul]

I see what you are saying. Kinda like the equivalent of ending the match statement with a

/// account for defaults
_ => V1((new_i128(inner), false)),

I did think about this, and in all honesty I am kinda on the fence on whether it would be appropriate for @substrate/calc to give a default Multiplier or not. We enforce third party chains to update their own fee configuration through the controller-configs. Meaning if they don't have a minCalcFeeRuntime in the configuration they wont calculate fees. Then they would have to add their match case inside of the rust package as well which allows for zero possible errors on our side or assumptions on another chains fee calculation.

But at the same time, as a package it makes sense for the Multiplier to have some kind of default value because then it can support more than just Polkadot, Kusama, parity testnets, and parity parachains.
