Unique uuids for every module of the ppl perception pipeline that uses ids

The tracker, the localisations, and the logger now all use the same uuid to easily associate them. See: https://github.com/strands-project/strands_perception_people/issues/72 which requires these messages to be updated.

Also added some comments and the Logging messages now contains the whole PedestrianLocalisation message but the poses and ids are still on the top level to allow easier usage.
