Bisect_ppx 1.3.0

Planned to break in the future 2.0.0

• The Ocamlbuild plugin will be factored out into its own OPAM package bisect_ppx-ocamlbuild, and the ocamlfind package will be changed to also have that name, instead of the current bisect_ppx.ocamlbuild. The new OPAM package is available now, since Bisect_ppx 1.3.0 (#146).
• Delete ocamlfind package bisect_ppx.fast. It is a little-used alias for package bisect_ppx (#144).
• Delete ocamlfind package bisect_ppx.plugin. It is a little-used alias for bisect_ppx.ocamlbuild (#144).
