GstAnalyticsGroupMtd

This type of metadata define a group of GstAnalyticsMtd. It allows to describe results as composition. Group members are ordered within the group and the semantic_tag allow to define a specific group meaning. For example with a semantic_tag = "posture/hand-21-kp", first member represent the "wrist", second is the thumb first joint.
