Point cloud attributes

[ftoromanoff]

• Add the extraction of scan angle values for las file (in LASloader.js)
• Add new point mode for visualisation of point cloud data:
  • ELEVATION, RETURN_NUMBER, RETURN_TYPE, RETURN_COUNT, POINT_SOURCE_ID and SCAN_ANGLE.
• Add new color scales:
  • one for discret values
  • several gradient for continuous data

It seems to break potree's examples:

• potree_25d_map.html :

  PotreeDebug.js:8 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading '__folders')
  at getController (PotreeDebug.js:8:1)
  at hideController (PotreeDebug.js:19:1)
  at setupControllerVisibily (PotreeDebug.js:28:1)
  at Object.initTools (PotreeDebug.js:147:1)
  at onLayerReady (potree_25d_map.html:105:39)

• same error in potree_3d_map.html when changing styling display mode

Fixed. I didn't pay attention that potreeDebug was used in other example. I made it more flexible to the folder name, instead of having it hardcoded.
