A macro to define Rutie methods, which uses rutie_serde to deserialize arguments and serialize results.

In comparison to rutie::methods!, this macro:

• Attempts to use rutie_serde to deserialize into the required type for each argument.
• Allows methods to return either Result<T, E> or T, where T: IntoAnyObject and E: IntoException. Errors are safely raised as Ruby exceptions and successful computations are serialized into Ruby objects using rutie_serde.
• Catches any panics that occur during the execution of each method’s body, and re-raises them as a Ruby exception.
• Catches any errors that occur during rutie_serde deserialization/serialization and safely raises them as Ruby exceptions.

It accepts an extra exception_class argument, which should be an expression resulting in a rutie::Class which is used to instantiate exceptions that are raised from panics.
