A tweaked keymap for Redox

I copied fculpo's layout and made a few modifcations more suited for my own needs. In general it seems to be a fairly straight foward adaptation of a standard QWERTY full size keyboard. At least for me.

Changes to the default keymap

Keymap changes from the default keymap are:

Move GUI (SUPER) key to where default left CTRL is
Move /? into usual location next to right SHIFT - the default flash from Falbatech put \| here (might not be the Redox default?), which felt unintuitive
Put \| into bottom-left spot where GUI (SUPER) was - had to go somewhere and this bottom-left placement sort of balances with the almost bottom-right /?
Change default ESC into ESC on tap, CTRL on hold - for the love of the UNIX-ey CTRL key location and to keep ESC in the original position
Add F11 and F12 keys to two layers - needed on macOS if you want to control volume up and down from your keyboard (not shown, on a different layer)S
Access ADJUST layer by holding either END or PAGEUP off default layer.

Changes by KL1RL are:

Remove the right hand CTRL combo key, it was bugging me.
Add Brightness Up and Brightness Down on the right hand thumb cluster on the ADJUST layer.
Add Mute, Vol Down and Vol Up on LH thumb cluster also on the ADJUST layer.
