Config notification/toast sound (#179)

* try adding config to load different sound

looks like include_bytes!() doesn't take a variable parameter, so will need a different solution lol.

* no errors in loading, but toast.rs now has a lifetime issue

* hey, config toast sound works now!

the sound is loaded in AppState now, since Toast are created in several different places at different times, and i don't want to load the sound every time a toast is made.

also put back the original sound since i accidentally commited my custom one.

* clean up

* change custom toast sound leak to happen on load rather than every play

* move toast sound loading into a function

so it can be reused in the future, for example if we want to load arbitrary keypress sounds or other [u8] data.

* remove label from try_load_bytes, return early when failing
