[new release] yojson and yojson-bench (2.1.1)

CHANGES:

*2023-10-10*

- Make `Basic`, `Safe` & `Raw` seperate compilation units that get exposed by
  the main module as suggested by @hhugo to enable JSOO to discard unused
  modules. No API changes should be observable. (ocaml-community/yojson#84, ocaml-community/yojson#167 @Leonidas-from-XIV)
- Removed forward refs in the parser to make dead-code elimination in JSOO
  better (ocaml-community/yojson#168, @hhugo)
