Add --throttle option.

Browse source 
This gives access to the existing throttling behaviour when reading
from a file with --interactive, without needing to actually have
--interactive.

This is useful when testing, as without --throttle samples will be
processsed much faster than real-time, which can produce different
results with e.g. aircraft/filter expiry times and position/speed checks.
