We have ~5 years of proof that we'll probably never extend Dict with more options. Breaking the classes into makes both a little faster (no options to check), and we remove some options in FoldDict that are never used (from/from_array). A possible next step is to fine-tune the Dict to use Map internally. Note that the TypeScript types for FoldDict are now more specific (requiring string keys). Of course, this isn't really enforced until we convert other modules to TS.
