ErgoDox EZ "jafo" Configuration

This is a layout based on the ErgoDox Ez default layout, but with some customizations I made for my use-case. I use Linux, vi and the i3 window manager, so I made these changes:

• Arrow keys laid out in vi positions in media layer.

• Esc (tap) and Win (held) to the left of A. i3 uses Win key for navigation and having that be symmetric on the left and right makes it easier.

• Grave accent below equals, I was having a hard time using ~

• Layer 2 switch below the L1 switch, so I can go into a mode where I get arrow keys under my vi motion fingers.

• Making the Ctrl (held) and Esc (tap) on my thumbs symmetric. Not sure I need that with the Esc left of A and Ctrl on the Z and / keys when held...
