Stick/Leverless layout with toggle Extra and flipped U/D inputs

It's a button layout that has Arika's suggested button layout for stick/leverless users but where R2 (the default Extra button) is set to be a toggle (so now you don't have to have it always pressed) and where the U/D inputs are flipped when Extra is toggled on (so that you can lock a piece in place by hitting down, as you normally would in TGM rules). The layout is a bit janky due to some quirks with Steam Input's behavior, you have to hit R2 once before it'll toggle properly.
