Vendored sliceutil breaks with go modules

[mgilbir]

When go getting the package in a project using go modules in go1.11, I get:

$ go get "github.com/milochristiansen/lua"
go: finding github.com/milochristiansen/lua v1.1.6
go: downloading github.com/milochristiansen/lua v1.1.6
go build sliceutil: no Go files in

When building, the error is cannot find module for path sliceutil

Possible solutions would be, bringing the sliceutil package into the project (out of the vendor directory), or if sliceutil is meant to be an external dependency it could be made available in another repo.

Yeah, that package is a lazy hack I pulled in from some of my private code. I should either integrate it properly or just redo the places that use it to be less hacky.

One way or another it will be gone either today or tomorrow.

Wow. Thanks for the quick fix! 🙇
