Add the HeartbeatTimer class to track a single heartbeat for a single link.
For every new received heartbeat an instance of the class is created.
Every instance emits a signal if it timed out or the timer is restarted.
Each vehicle then decides based on all different signals which link is the
priority link.

Converted Structure Scan to use CameraCalc such that it now works with
camera specs.

Also hand carried text to speech changes from Stable to master. Plus
unit tests for that.
