missing v2 folder

[c-mcallister]

For repositories that provide libraries that are imported into other projects, if it needs to support multiple major versions at the same time (which is common) then the idiomatic go approach is to create a v2 folder to put it in (with its own go.mod and go.sum)

This should be referenced somewhere - possibly in the /pkg folder? or possibly by adding a /v2 folder to the root - as both are valid I think
