Safe calculation of muon crossings

This MR removes the muon crossing factor to estimate the number of crossings. Instead, it precalculates the number of crossings by running another kernel.

• muon_populate_tile_and_tdc now calculates the number of crossings. It precalculates dev_muon_tile_used_t and dev_station_ocurrences_sizes_t.
• muon_station_ocurrence_prefix_sum runs right after muon_populate_tile_and_tdc and before muon_add_coords_crossing_maps.
• Now, muon_add_coords_crossing_maps knows how many hits there are exactly.

Closes #369 (closed).
