Both frames of a waypoint used to take the colour frame's time, which made
the thermal one look taken at a moment it was not: it is the newest frame the
camera had, up to max_frame_age_ms old. Each file and CamEvent now has the
time its own frame reached the host; the two of one waypoint share hdg/pit and
are at most that age apart. The docs say to pair them by that.

A TarisIR mini (driver = taris) is a second camera source behind a
CompositeCameraSource: the colour camera is asked first, then the thermal one
for its newest frame, and both frames carry the colour frame's timestamp.
Counts are saved 16-bit lossless under TIR/, and the CamEvent gains cal,
missed, tmax, tmed, hotx and hoty (docs/mqtt-api.md). The SDK is declared in
IrbgrabApi.h and loaded with dlopen, so no SDK file is in the repository; a
missing or unreachable camera stays offline (Health cams_offline) while the
scan goes on. scripts/fgc-setcap gives the binary cap_net_raw after a build.
Built and tested in an Ubuntu 22.04 container (mock, MQTT, Vimba+MQTT,
534/534), plus a mock run with RGB/TIR pairs. Not yet run against the camera.
