Create dedicated docker image (#59)

This makes it possible to test formatting changes using CSharpier. To
test formatting, both Rust and Dotnet must be installed in the same
docker image. This is because `--library` mode runs `cargo metadata`
command, and formatting runs `dotnet-csharpier` command.
