Add better string validation

Cases with JsonDecoder.string make the key required to be a string, but sometimes the string can be an empty one e.g. "". Another case, would be when the value can be any string other than certain values e.g. would fail on "STOP".

In my case I need to ensure empty strings for required keys fail. Is there a way to do that?

In my eyes I see 2 ways to solve this 1) an opt-in feature to fail on an empty string value in case of a required key, 2) add an optional exclude value array for strings e.g. { exclude: ["value1", "value2"] }
