Draft: Use arrays in HybridSeeding
Related to !3544 (closed) upon which it builds.
Changes the structure of the xHits, making hit order more explicit, a la Allen. This allows for a much more compact clone removal. This leads to a 3-fold acceleration of the seeding in lead-lead.
Finally, in the course of the development of this MR, some options seemed to decrease the number of output tracks quite substantially, leading to an overall speed-up of 8 and a slight reduction in ghost rate (down to 91%). This is being investigated.
