[Feature] show duration of access in logs

[KosRud]

Describe the feature you'd like :

In log entries show not only the time when the app accessed the camera or microphone, but also how long did it keep using it.

Additional context :

Say I used Shazam several times a day so I think nothing of it when it comes up in logs. If I saw that one of the log entries said "1 hour of non-stop listening" that would raise my concern.
