Nickel Language Server

https://github.com/tweag/nickel

`nls` can be installed with nix, or cargo, from the Nickel repository.
```sh
git clone https://github.com/tweag/nickel.git
```

Nix:
```sh
cd nickel
nix-env -f . -i
```

cargo:
```sh
cd nickel/lsp/nls
cargo install --path .
```

In order to have lspconfig detect Nickel filetypes (a prerequisite for autostarting a server),
install the [Nickel vim plugin](https://github.com/nickel-lang/vim-nickel).
