Usability readParam!EnumType should verify some properties

- should verify than the .min and .max of the enum used match the parameter
- currently you can make a mistake in the number of labels, or a mistake in the enum type.

Start by locating the readParam!EnumType entry point and inspect how it currently handles the parameter and enum type. Done means mismatched enum min/max values, label counts, and enum types are detected and reported; the issue does not name a test or file to run.
