Elixir support

[setop]

I don't know how much effort it cost to support a new language.
But I'm working on a large Elixir code base and I would love to be able to Grit to refactor it reliably.

Thanks for your interest! We currently prioritize languages for our commercial customers, but if you'd like to take on adding this yourself the process is described here: https://github.com/getgrit/gritql/blob/main/CONTRIBUTING.md#adding-a-new-target-language

I made an attempt, getting inspiration from what exists for ruby as these languages are not too far from each other.

At some point I even managed to have it compiled and passing tests.

But is fails at matching simple code:

$ cat hello.exs 
IO.puts "Hello"

$ ./target/debug/grit apply --dry-run --language=elixir '`IO.puts "Hello"` => `IO.puts "Bye"`' hello.exs
Processed 1 files and found 0 matches

whereas

$ cat hello.rb 
puts "Hello"

$ ./target/debug/grit apply --dry-run --language=ruby '`puts "Hello"` => `puts "Bye"`' hello.rb
hello.rb
    -puts "Hello"
    +puts "Bye"

The problem is usually missing contexts. If you open a draft PR I'm happy to try debugging.

That's indeed the part of the guide I understood the least ;)

With great pleasure.
