Previously this code was just crashing if I attempted to decode JSON with a field missing. Now it will crash with an error message that indicates more precisely what is actually happening.

@genixpro looks like this breaks the test suite:

raise TypeError( f"The JSON data is missing the required field '{field.name}' when decoding {cls.name} from JSON." )

Maybe you can have a look why?
