From cdac4ed1ce81b76e6684f778fd07c8ebdacce556 Mon Sep 17 00:00:00 2001

Subject: Configure for importing from C/FFI

* Add `#[repr(C)]` on `HeadphoneButton` to hopefully be able to use it
  outside Rust
* Add `#[no_mangle]` to `run_key_action()`
* Export `run_key_action()` as a public function
* Build the crate as a static library

(But holy cow, a 19 MB library file?)
