Import cycle when using go-samsung-exlink as a go module

[zbrozek]

I'm probably just exposing my lack of experience with go modules, but when I try to build the example main package referencing github.com/mgoff/go-samsung-exlink it fails to compile with error imports github.com/mgoff/go-samsung-exlink: import cycle not allowed. Maybe I'm just setting up the environment or invoking the build incorrectly?
