(first working dynload test with compilation done by manual calls to ocaml) A few pieces of the puzzle: * Loading of interfaces only from Catala files * Registration of toplevel values in modules compiled to OCaml, to allow access using dynlink * Shady conversion from OCaml runtime values to/from Catala expressions, to allow interop (ffi) of compiled modules and the interpreter
