Here, we're expected vars_found to correspond to mole fractions and we'll add mass fractions.

vars_found should have things like X_N, etc. The prefix will be "X_" for mole fractions. Then, we'll add mass fractions, using the corresponding names in the SpeciesMassFractionsFEVariables. We'll match them based on the species names.

We'll search for mole fractions: X_<species_name>.

We extract the species name from var_names and then set the corresponding vars_to_search_for to X_<species_name>.
