Module energy_injection

Energy injection scenarios for the early Universe.

Provides heating rate functions Q̇(z) for various physical mechanisms:

• Single (quasi-instantaneous) energy injection
• Decaying particles (heat or photon channel)
• Annihilating dark matter (s-wave and p-wave)
• Monochromatic photon injection
• Tabulated heating / photon source (from external data)
• Custom (user-supplied function)

All heating rates are expressed as d(Δρ_γ/ρ_γ)/dt in units of 1/s.
