Draft: Use arrays in the seeding rather than hit vectors
This MR was originally intended to make clone killing more efficient in terms of CPU, but might also speed up the seeding as a whole.
As this stands, we lose 0.2% efficiency across the board but remove 25% of the ghosts. It is yet unclear why the XZ part is affected at all, since this change should be transparent.
