Possibility to add custom type handlers

[shavrova]

Hi there. Very useful project, but not enough types for me to use unfortunately. I can create a PR to add UUID, LocalDateTime etc, but the problem is I need to populate my record with custom enum type and I don't know how to do it. Fork also is not an option because this enum type is something generated (not in runtime) and I don't know that it will be.
I was thinking something like that (but I'm not sure it even possible since it uses reflection):

RandomJooq.addTypeHandler(MyTypeHandler.class);
MyJooQRecord myJooQRecord = RandomJooq.randomize(MyJooQRecord.class);

I can do it myself if you'll give me a hint, I didn't work with reflection before and from first look I don't know if it's doable to pass a class here like that.
