ms_between()

uint64_t fsw::calibration::anonymous_namespace{CaptureWindow.cpp}::ms_between	(	uint64_t	later_ns,
		uint64_t	earlier_ns )

Saturating difference — clocks are unsigned and callers may pass a now that predates a sample (a reordered packet, or a test driving times by hand).

Wrapping here would turn "41 ms old" into "584 million years old" and reject a healthy capture.
