Start building a music player server (#17)

The very beginnings, with a very basic application architecture, for a music playing server on a headless system.

This also adds my new Flow library, which I'll be wanting to use in a variety of places.

This is a library to help with application control flow, separating fatal errors from normal recoverable errors. This is almost entirely inspired by [Error Handling in a Correctness-Critical Rust Project](https://sled.rs/errors.html) in the sled.rs library.
