Support Elixir

[zentetsukenz]

To be fair, I think I shouldn't open this issue but just in case the PRs to support Elixir were covered by the amount of issues/PRs and didn't get attention enough. I do understand the amount of PRs to review so, just in case there are these 2 Elixir PRs (looks like ready to merge).

• feat(extraction): Elixir language support (.ex/.exs) #871
• add support for elixir #228

I think it would be great that they get some attentions so we can have support for Elixir.

Thanks for this great tool!
