Fixes:

• iOS/android with TOF/LiDAR should use Vis/PnPVarianceMedianRatio=2 #1401
• IOS: Request: More optional values in “Max features extracted” #1407
• iOS: marker detection broken? #1455
• IOS: Possibility of Creating LAZ Files on iPhone? #1374

New features:

• Measuring tool. See usage: 0.21.11 iOS release: New basic measuring tool #1468
• Texturing untextured surfaces with nearby Colors within the iOS App #1358
  • Currently implemented like Meshlab is rendering, so we see seams between texture and coloured vertex. That may be useful or not, maybe add a rendering option to not show them. This can be done in the fragment shader, by only applying color when texcoord >= 0.99

Review:

• The measuring button shows up when visualizing optimized point cloud, but cannot be used. Hide button if we are visualizing a point cloud.
• When export in LAZ format, we shouldn't zip the file afterwards, it won't be smaller anyway. Just export directly as laz instead of zip.
