Maestro and Rupay card type detection support

[nagarro-mohitpadalia]

Can we have the card type detection for maestro and rupay cards.

looks like on line 119 (SwiftLuhn.swift)

for i in CardType.amex.rawValue...CardType.jcb.rawValue {

}

This iteration should go upto CardType.mir to support the card validation for maestro and rupay.

@nagarro-mohitpadalia thanks for pointing out the issue! Is this something you'd be able to pick up? When the code was implemented originally, CaseIterable didn't exist. Perhaps we can leverage that?
