fix: use getPosASL for sector positions (#101)

Sector tracking used getPosATL which gives height relative to terrain,
inconsistent with the rest of the capture pipeline (captureLoop,
projectile tracking) which all use getPosASL. For accurate 3D rendering
without a heightmap, all recorded positions must be in the same absolute
coordinate system. Also fixes the example comment in handleCustomEvent.
