This is designed for libraries to pass simple configs with just a String.
e.g.
Passing "compression_type=zstd;level=3" instead of `Config::Builder::new()::with_level(3).with_type(CompressionType::ZSTD).build().unwrap()`?
Passing "bind=0.0.0.0;port=8080" to SocketServer instead of `(Option<InetAddress>, Option<u32>)` tuple?
Your choice.
