107 increase the number of processes in the process map

[EinarElen]

This resolves #107 by increasing the number of processes that we give distinct name/ids to. This adds inelastic versions for neutrons, kaons, pions, and protons. This is useful for identifying the fates of particles produced in complicated reactions (e.g. PN-daughters)

The additional mappings are

• $n + Z \rightarrow X$: neutronInelastic
• $n + Z \rightarrow Z^*$: neutronCapture
• $p + Z \rightarrow X$: protonInelastic
• $K^+ + Z \rightarrow X$: kaonInelastic
• $K^- + Z \rightarrow X$: kaonInelastic
• $K^0_L + Z \rightarrow X$: kaonInelastic
• $K^0_S + Z \rightarrow X$: kaonInelastic
• $\pi^+ + Z \rightarrow X$: pionInelastic (Note: pi0 doesn't have an inelastic process due to its short lifetime)
• $\pi^- + Z \rightarrow X$: pionInelastic
• $\mu^- + Z \rightarrow X$: muonNuclear
• $\mu^+ + Z \rightarrow X$: muonNuclear

As well as the new "Primary" category which is assigned if the particle has no parent process and the parent ID is 0.
