clusters/emission.py: Fix units/dimensions problem
NOTE:
Since we just substitute ``p`` (electron momentum) for
``γ`` (electron Lorentz factor), i.e.,
N = int_p n(p) dp = int_γ n(γ) dγ ,
therefore the coefficient ``sqrt(3) e^3 B / (m c^2)`` does NOT need
modification (e.g., multiply an extra ``m c``)!
