pcl: disabled PCL_ENABLE_SSE to avoid runtime errors with eigen etc. see https://github.com/PointCloudLibrary/pcl/issues/4258#issuecomment-656138999

Known issues until now

• some issues related to AffordanceKit/VisionX: malloc error when loading PrimitiveExtractor gui widget
• issues related to cartographer (remember the demo preparations ...)
• even directly in simox I received some runtime errors
• navigation: error: eigen dense assignment loop / swap assign wtf

I'm still investigating whether the issues are gone
