feat(priming): Priming now uses solver to initialize species abundances

Instead of a complex system of identifying dominate channels and
approximating abundances based on that, priming now simply ignites a
basic network at 1e7K for 1e-15s. This is an effective approach to prime
relevant species while being short enough to not change the abundance of
any fuel species.
