[new release] crunch (3.2.0)

CHANGES:

* Make crunch reproducible: use a Map.Make(String) instead of Hashtbl.
  Iterating over the former is guaranteed to be sorted over the keys.
  (mirage/ocaml-crunch#51 @hannesm)
* The state (Map.t) is passed explicit to `scan_file`, `output_implementation`
  and `walk_directory_tree`. The value `empty` is provided to construct an
  empty `t`. (mirage/ocaml-crunch#51 @hannesm)

+synopsis: "Convert a filesystem into a static OCaml module"
+description: """
+`ocaml-crunch` takes a directory of files and compiles them into a standalone
+OCaml module which serves the contents directly from memory.  This can be
+convenient for libraries that need a few embedded files (such as a web server)
+and do not want to deal with all the trouble of file configuration.
