Filter joystick dead zone values

In response to a request on reddit. WMR vrclient will now filter out deadzone values for the joystick. This can be useful if your joystick is not calibrated correctly. The deadzone can be changed from the json file.

Flip X/Y and swap controllers

Added new options:

"flipXY": support for flipping x/y input (for youtubeVR)
"swapControllers": support for swapping controller input (requested on reddit)

(Speculative) Support for Onward

This release adds a new setting "mapRightUpDownToLeftPadClick" as requested on reddit for the playing of Onward... Which I don't have, so YMMV ;)

Release 0.0.6

Potential fixes around event generation

Release 0.0.5

This release adds the size of the dead zone to the configuration file.

Third release

This fixes the issue with Steam crashing if the runtime is installed during start up

Fouth release

This supports older versions of the API so ADR1FT now works
