Add Mac M1 build target

[L4vlet]

When using the library on Mac ARM machines, we faced problems with compilation.

Following the fixes in other NIF library, this PR adds a build target for the darwin architecture.

Original error:

** (Mix) Could not compile dependency :xxh3, "/Users/andrey.pozdnyakov/.asdf/installs/elixir/1.16.3-otp-26/.mix/elixir/1-16/rebar3 bare compile --paths /Users/andrey.pozdnyakov/projects/dummy_elixir/_build/dev/lib/*/ebin" command failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile xxh3 --force", update it with "mix deps.update xxh3" or clean it with "mix deps.clean xxh3"
