Feet [v3 Beta] patch notes.

Thank you community! We are listening all your bug reports and suggestions. I couldn't be possible without you.

• Fixed Left/Right controller detection in HTC Vive pro headset with Valve Index Controllers. It should fix the locomotion not working issue recently reported by some users in the forum.
  
• Fixed walking backwards by leaning back calibration. NaLo was not detecting the neck position correctly.
  This issue could produce walking backwards by default in some cases reported in the forum.
  
• Fixed a rare case where some trackers would appear duplicated in Natural Locomotion. This is not the same than duplicated controllers in the "Convert SteamVR controller to tracker" UI.
