feature wish: reset button for Average Levels on interface

[HorNet505]

I wish there would be a simple reset button on the interface itself, rather inside the menu to reset the average Levels to zero.
I have to do it frequently on each reference track

and even keyboard shortcut should be perfect as I reset averages often after changing parameters on some audio device, so hitting key would be fastest way how to do it.

ok, we are going to implement:
F5 = Reset Average Level
F6 = Reset Max Level
