Add proton light quenching

Description

Please provide a detailed description of the changes this pull request introduces.

This PR implements a light quenching factor for protons. The currently used modified box model is in agreement with experimental data (Ref Doke et al., Jpn. J. Appl. Phys. Vol. 41 (2002) pp. 1538–1545.) for MIPs but not for protons. The dotted line from the figure below shows the modified model prediction in the absence of electric field, which agrees with Figure 2 from the previous reference for MIPs but not for protons. Assuming the same light attenuation factor due to the electric field for protons and electrons (~0.6), the expected relative scintillation yield (L/L0) for protons can be calculated as the value quoted from the reference ~0.81 corrected by the electric field attenuation factor, that is L/L0 ~ 0.49.
From the figure below, we can see that the relative scintillation yield currently predicted by the modified box model is ~0.7, so we need an extra quenching factor of 0.7 to match the expected L/L0 ~ 0.49.
