Julia 1.6 will be the new LTS. In Julia 1.6 and later, TOML is a standard library. Therefore, I don't think that we need to keep maintaining this repository as a package for Julia 1.5 and earlier.

@KristofferC What do you think about:

1. Archiving this repository.
2. All future issues and pull requests will be made directly to the JuliaLang/julia repo. In other words, the TOML stdlib (https://github.com/JuliaLang/julia/tree/master/stdlib/TOML) will be developed just like any other stdlib that lives inside the JuliaLang/julia repo.
