go-ctags: universal-ctags wrapper for easy access in Go

Note: This library is meant only for Sourcegraph use.

To improve type:symbol results in Sourcegraph, for languages with high quality Tree-sitter grammars, prefer adding support in scip-ctags in the Sourcegraph monorepo over adding support in this repo.

Adding new ctags flags

Add/modify appropriate .ctags files in ctagsdotd and re-run ./gen.sh at the root of the repository.

Testing
