Mud's G2R for Steam Deck

This a modified version of JEC's layout. I have removed the buttons on the left trackpad, as they are easily available on screen with this improved mouse control. Press button on right pad for left click, left pad for right click. Instead of clicks, the triggers now offer Tab details, the right trigger being a toggle. Keyboard and magnifier have been added to two of the back grips, while the others allow for rotating the camera.
