Overhall of the seed extraction kernels:
Now extract all paths through the graph into path_store <- size can be counted in the CCA, so no more exceedable maximums for those allocations. This reduces both the allocation size and now only an int2 is passed in and out of memory while branching through the graph, rather than the large edgeState (80 bytes).
All paths are then fit to obtain a quality score for disambiguation rather than fitting only some at a time.
One bidding round selects only the highest quality seed starting at each edge. Then the same iterative bidding occurs to pick the best seeds as before. The change to the first round improves seed purity and high pT efficiency.
Reduces the seed extraction kernel times from ~25% to ~5% of kernel time.
