[bug#49203] [PATCH 1/2] gnu: Add ocaml-uri-sexp.

[Adu O'Hara]

Thanks for the patches!

There is already an `ocaml-uri`. How about updating that to 4.2.0 
(currently at 4.1.0) and let `ocaml-uri-sexp` inherit from 
ocaml-uri with #:package set to "uri-sexp"?

Another alternatively: remove the #:package argument from 
`ocaml-uri` so that all packages are built (`uri`, `uri-sexp` and 
`uri-re`).
