Go 1.13 and up enforce import paths to be versioned if a project contains a go.mod and has released v2 or up. The current v2.x branches (and releases) do not yet have a go.mod, and therefore are still allowed to be imported with a non-versioned import path (go modules add a `+incompatible` annotation in that case). However, now that this project has a `go.mod` file, incompatible import paths will not be accepted by go modules, and attempting to use code from this repository will fail. This patch uses `v3` for the import-paths (not `v2`), because changing import paths itself is a breaking change, which means that the next release should increment the "major" version to comply with SemVer (as go modules dictate).
