Possibility of adding go bindings

[mark007]

I am loving this repo, and am trying to use it to write a validator for some helm charts using go. Is there any possibility to add a go binding? I tried using this fork which does have go bindings and it works well but has fallen quite behind so doesn't have lots of grammar updates from this repo.

But it does have go bindings. I made an attempt to combine the bindings from qvalentin's fork into this repo but its beyond my expertise :)
