Add Zig support

[Antman261]

Depends on cursorless-dev/tree-sitter-wasms#25

[Antman261]

The scopes are showing up as unsupported in the language, which I believe means that the tree parsing is working correctly:

Not necessarily. The best way is to actually test the parse tree. Open a zig file and run the parse tree action. You should get a markdown file with the source code and parse tree in it.

Does this look correct?:

Cursorless parse tree

test.zig [3:10-3:12]

le

(source_file
  (function_declaration
    body: (block
      (variable_declaration
        (identifier)
      )
    )
  )
)

source_file [0:0-29:0]
  function_declaration [2:0-28:1]
    body: block [2:19-28:1]
      variable_declaration [3:4-3:29]
        identifier [3:10-3:12]

I don't use zig personally, but you definitely got a valid parse tree back. :)
