Bass Lyre Bridge

Inspired by the great [Nicolas Bras](https://www.youtube.com/watch?v=lbgwWNI4xvI), this is a bridge piece meant to sit atop a drumhead and pass strings for sound conductance. I built one, it's awesome, thanks Nicolas :)

Customize for your drum and strings! Surely it could use some improvements, I'll come back around to version 2.0 one day.
