DyteParticipantMap

This is a map of participants, indexed by participant.id (a participant's peer ID). This map emits an event whenever a participant present in the map emits an event. For example, when a participant is added to this map, a participantJoined event is emitted from the map. When a participant object emits an event videoUpdate, the map re-emits that event (provided the participant is present in the map).
