RecordsTracker<Record, Update> mixin

Tracks changes of individual records in the list.

The records must be able to provide a Stream for tracking (as records, for example, Cubits from package Bloc can be used). When the list is changed, the new records must be registered for tracking by calling registerRecordsToTrack.
