two dpad shifting method base on 1.03

Two DPAD shifting methods, "Right Joystick Press + Left Joystick" and "Left Joystick Press + Right Joystick", are added.
Non-Oculus users can benefit from these methods in case they are unwilling or unable to use the gesture-based methods, e.g., when they are lying in bed.

The new methods will disable the R3 and L3 mapping respectively, except one can press L3 + R3 to toggle the UEVR menu.
When "Left Joystick Press + Right Joystick" is used, snapturn is temporarily disabled when the left joystick is pressed.
Tested with a few games.
This version is roughly based on UEVR 1.03
test device: Pico 4 + VD openXR

alternative dpad shifting method

Add another DPAD shifting method (Right Joystick Click + Left Joystick) for controllers without thumbrest, e.g. PICO.
R3 is disabled if this method is active, except that you can still press L3 + R3 to toggle the UEVR menu.
Based on UEVR 1.2, Just replace the dll.
