Remove dependency on Pkg

Pkg = "44cfe95a-1eb2-52ea-b672-e2afdf69b78f"

Pkg itself is quite large and it would probably be better to just use TOML.jl directly.

We currently use it to extract some version information. But this is not vital (just convenient), so if it would make our life easier, I think there's no hard reason not to simplify this.
