Title: triplet-based seeding for iter5 and iter6

This PR changes iter5 and iter6 from pair-based seeding to triplet-based.
See this talk for more details: https://indico.cern.ch/event/292572/contribution/1/material/slides/0.pdf

Expect differences in reconstruction, with similar physics performance and large speedup in timing.
