* Addressing #1407

* Export: Added colored OBJ options

* fixed index_t not existing on focal

* Fixed Settings not applied after restoring to all default settings witohut restarting the app (Marker detection not working issue #1455 )

* Marker detection: Fixing wrong depth used when rgb and depth image sizes cannot be divided exactly one from the the other #1455

* Added Marker Max Range option (default 1m)

* Added OBJ texture policy option (keep color on textureless polygons)

* Added texture/color blending option directly in the app. Added LAZ export option.
