we are going to need to modify each of the networks.
currently, they all take in X_k and return d(Y_k)/dt, and the Jacobian in terms of Y_k
We are going to convert these all to be in terms of X_k. If the net internally uses X_k, then we just take out any conversion to molar fractions.
If the net works with Y_k internally, then we will need to multiply dY/dt by A to get dX/dt. The Jacobian conversion is a little tricker, but can be seen in bs_jac.F90 as:
do n = 1, nspec_evolve
bs % burn_s % jac(n,:) = bs % burn_s % jac(n,:) * aion(n)
bs % burn_s % jac(:,n) = bs % burn_s % jac(:,n) * aionInv(n)
enddo

actually... we can start by still having the networks return dY/dt, since in the *_rhs.f90 (for each integrator) we have a conversion like:
if (.not. integrate_molar_fraction) then
burn_state % ydot(1:nspec_evolve) = burn_state % ydot(1:nspec_evolve) * aion(1:nspec_evolve)
endif
