Fixing the following error:

Traceback (most recent call last):
  File "/path/to/envs/pydamage/lib/python3.12/multiprocessing/pool.py", line 125, in worker
    result = (True, func(*args, **kwds))
                    ^^^^^^^^^^^^^^^^^^^
  File "/path/to/envs/pydamage/lib/python3.12/site-packages/pydamage/damage.py", line 215, in test_damage
    ) = al.compute_damage()
        ^^^^^^^^^^^^^^^^^^^
  File "/path/to/envs/pydamage/lib/python3.12/site-packages/pydamage/damage.py", line 125, in compute_damage
    CT_damage_amount[CT_pos] = CT_counts / C_counts[CT_pos]
                                           ~~~~~~~~^^^^^^^^
IndexError: index 8 is out of bounds for axis 0 with size 6

This error occured in edge cases when the indicing of C_counts by CT_pos was discordant.
