 A JSON parser that parses `BTJSON` into concrete `BTPaymentMethodNonce` objects. It supports registration of parsers at runtime.

 `BTPaymentMethodNonceParser` provides access to JSON parsing for different payment options
 without introducing compile-time dependencies on payment option frameworks and their symbols.
