Title: Update PointCloudImageExtractors and pcd2png tool

This pull request adds two new features to the point cloud to PNG converter:
* Paint pixels corresponding to NaN (infinite) points with black;
* Use the [Glasbey lookup table](http://fiji.sc/Glasbey) to paint labels with a fixed set of highly distinctive colors.
