/**
* Reads specified scans from given directory in
* the file format Riegl Laser Measurement GmbH
* uses. It will be compiled as shared lib.
*
* Scan poses will NOT be initialized after a call
* to this function. Initial pose estimation works
* only with the -p switch, i.e., trusting the initial
* estimations by Riegl.
*
* The scans have to be exported from the Riegl software
* as follows:
* 1. Export point cloud data to ASCII
* Use Scanners own Coordinate System (SOCS)
* X Y Z Range Theta Phi Reflectance
* 2. Export acqusition location (after you have registered
* with the Riegl software)
* Export SOP
* Write out as .dat file
*
* @param start Starts to read with this scan
* @param end Stops with this scan
* @param dir The directory from which to read
* @param maxDist Reads only Points up to this Distance
* @param minDist Reads only Points from this Distance
* @param euler Initital pose estimates (will not be applied to the points
* @param ptss Vector containing the read points
