Subject: [PATCH] add mod file and bump major version

- continuation of module change from #52
- since your release tags are v2+ simply adding a go.mod file will cause
`v2.0.0+incompatible` versions in consumers
  - the go authors suggest bumping the major version to resolve this:
https://github.com/golang/go/wiki/Modules#incrementing-the-major-version-when-first-adopting-modules-with-v2-packages
    - after merge you should tag this repo with `v3.0.0`
  - you could migrate to `v2.1.0`, but this could cause consumer
breakage
  - this uses the major branch paradigm, but you could leverage major
subdirectory instead:
