Detailed Description

Shared data for all reverse-two-temperature-plasma reactions.

Holds a single-temperature ideal-gas "shadow" Solution built from the forward reactions only (so it contains no reverse/janev rates and cannot recurse).

This mirrors rizer's Python reference (ExtensibleTwoTempPlasmaRateData): the shadow is evaluated at BOTH the gas temperature Tg and the electron temperature Te (each a single-temperature ideal-gas state), caching the forward rate constants and equilibrium constants at each. A reverse reaction then uses \( k_{rev} = k_{fwd}(T)/K_{eq}(T) \) at the temperature named by its T: tag (Tg for heavy reactions, Te for electron reactions) – detailed balance at one temperature.
