Writing the samples/waypoints to UDDF export in a totally new way.
Previously the preparations for approximating waypoints was done for
every sample, now only for the events.
A few days ago it took 36 seconds for my test set of 8 dives to export
to UDDF. This optimization round took it down from 0m4.745s to
0m0.253s.
