vicon_transformer package

Wrapper around Vicon Datastream SDK that simplifies setup and access to the data.

Most relevantly, the ViconTransformer class can provide poses of all subjects relative to a configurable “origin subject”. This origin subject should be fixed in the scene (e.g. screwed to a wall), such that it cannot move over time. It then serves as a clearly defined origin of the scene, that is independent of the actual origin used by Vicon (which otherwise would need to be redefined after every re-calibration and is generally difficult to set precisely).
