HeadphoneKey: Get switching to mode working

* Update to latest dome-key-map, which handles in-mode internally using
  a `State` struct
* Make a `State *` ivar to store the current dome-key-map state, and let
  it do the work of mode handling

Currently doesn't handle exiting a mode, only entering one. But that
last part actually does finally work now, yay!

Still requires cleanup to get rid of the old `in_mode` handling.
