Release ppxlib.0.33.0

- Fix a bug where `Code_path.main_module_name` would not properly remove
  extensions from the filename and therefore return an invalid module name.
  (ocaml-ppx/ppxlib#512, @NathanReb)

- Add `-unused-type-warnings` flag to the driver to allow users to disable
  only the generation of warning 34 silencing structure items when using
  `[@@deriving ...]` on type declarations. (ocaml-ppx/ppxlib#511, @mbarbin, @NathanReb)

- Make `-unused-code-warnings` flag to the driver also controls the generation
  of warning 34 silencing structure items when using `[@@deriving ...]` on type
  declarations. (ocaml-ppx/ppxlib#510, @mbarbin, @NathanReb)

- Driver: Add `-unused-code-warnings=force` command-line flag argument. (ocaml-ppx/ppxlib#490, @mbarbin)

- new functions `Ast_builder.{e,p}list_tail` that take an extra tail
  expression/pattern argument parameter compared to `Ast_builder.{e,p}list`, so
  they can build ASTs like `a :: b :: c` instead of only `[ a; b ]`.
  (ocaml-ppx/ppxlib#498, ocaml-ppx/ppxlib#502, @v-gb, @NathanReb)

- Fix `Longident.parse` so it also handles indexing operators such as
  `.!()`, `.%(;..)<-`, or `Vec.(.%())` (ocaml-ppx/ppxlib#494, @Octachron)

- Add a `special_function'` variant which directly takes a `Longident.t`
  argument to avoid the issue that `Longident.t` cover distinct syntaxic classes
  which cannot be easily parsed by a common parser (ocaml-ppx/ppxlib#496, @Octachron).

- Keep location ranges consistent when migrating `Pexp_function` nodes from 5.2+
  to older versions (ocaml-ppx/ppxlib#504, @jchavarri)

- Fix `-locations-check` behaviour so it is no longer required to pass `-check`
  as well to enable location checks. (ocaml-ppx/ppxlib#506, @NathanReb)

+synopsis: "Standard infrastructure for ppx rewriters"
+description: """
+Ppxlib is the standard infrastructure for ppx rewriters
+and other programs that manipulate the in-memory representation of
+OCaml programs, a.k.a the "Parsetree".
+
+It also comes bundled with two ppx rewriters that are commonly used to
+write tools that manipulate and/or generate Parsetree values;
+`ppxlib.metaquot` which allows to construct Parsetree values using the
+OCaml syntax directly and `ppxlib.traverse` which provides various
+ways of automatically traversing values of a given type, in particular
+allowing to inject a complex structured value into generated code.
