What's needed to bump the SDK version?

[chrislatorres]

For the latest Lumin SDK version (v0.22.0), this error happens due to

In file included from ../exokit.cpp:10:
In file included from c:\Users\chris\github\exo2\exokit\deps\exokit-bindings\bindings\inc
lude\bindings.h:26:
c:\Users\chris\github\exo2\exokit\deps\exokit-bindings\magicleap\include\magicleap.h:40:1
0: fatal error:
      'ml_gesture.h' file not found
#include <ml_gesture.h>

That header file does not exist in v0.22, below is looking for the file in the sdk directory, it is only found up to version 0.20.

MagicLeap$ find . -name "ml_gesture.h"
./mlsdk/v0.19.0/include/ml_gesture.h
./mlsdk/v0.20.0/include/ml_gesture.h

From the release notes below:

ml_gestures.h is removed from the SDK, use ml_hand_tracking.h

Will need to update the usage in that case.
