Request/Enhancement: User selected audio as notification instead of spoken count down

[Eiion]

As the title says, if like to suggest adding the feature to allow the user select an audio file from the devices e.g. download folder used as signal for interval start/interval end/break end/session end signal.

While the sondern count down is an ok way to handle things something the user can select could be much less intrusive (think of a meditation or progressive muscle relaxation session) or much more intrusive (in life environments).
Also, it would be just nice if we had the option to use whatever sound we would like rather than only being able to use the spoken count down.

I'd fork the git and add/change the code myself but unfortunately I have no knowledge in coding.
