fix: wrap fragment parse & serialize as uncurried

resolves #296

the module signature was not wrapped, and the implementation was wrapped
in another fun that prevented the match in wrap_as_uncurried_fn from
working as intended

I also fixed a warning 53 with the @@tailcall attribute I was getting
for ocaml 5.1.1, maybe I ended up with different versions of something?
