HebiMobileIO Wrapper

[ennerf]

• Added HebiMobileIO wrapper
• Fixed a few places where mobileIO wasn't the default name
• Updated examples w/ new API

Differences to other APIs	Python	C++	MATLAB	Comments
set_snap	setSnap	setAxisSnap
???	disableSnap(axis)	setAxisSnap(axis, nan)
set_button_mode	setButtonMode	setButtonToggle
set_button_output	setButtonOutput	setButtonIndicator
set_text	sendText	addText
get_last_feedback	getLastFeedback	getFeedback	getLastFeedback and getOrientation from the same feedback seems inconsistent
update	getState	update	simplifies non-blocking calls
		initializeUI	resets the UI to the initial state
		getOrientation	3x3 based on IMU. Sometimes IMU is preferrable over AR, so I think it makes sense to add separate methods
get_orientation	getOrientation	getArOrientation	3x3 based on AR
get_position	getPosition	getArPosition	3x1 based on AR
		getArPose	4x4 based on AR
		(static) findDevice	repeatedly searches until the device is found. Not sure this is necessary, but every matlab demo uses it.

• The axis/button states are returned as the normal IO feedback and a struct with the diff states. Off, ToOn etc. enum constants are a pain to deal with in MATLAB and it's more natural to just look at the raw/diff values.
• Should setAxisValue be renamed to setAxisPosition ?
