Is your feature request related to a problem? Please describe.

get_segments becomes really slow as the amount of annotation segments gets large. most of the work is probably done by clip_segments.

Describe the solution you'd like

traverse segments only once rather than once per annotation segment
maybe us multithreading if necessary
keep things vectorised...
do proper benchmarks (and a bit of profiling to make sure the issue is really clip_segments)
