Added new ways to select exactly what types of reactions (strong, beta+, beta-, electron capture, positron capture, or any combination thereof) can be turned on at network construction time. There are a few quality of life masks added as well such as weak which addes all weak type reactions, and all which adds weak + strong reactions. The default is to just add strong reactions for now.
Fized stoichiometry matrix initialization, added penames to reablib reactions, began work on LogicalReaction to sum the contributions of different fitting functions provided by reaclib
This is a very basic wrapper implimentation currently. This is sufficient to lock the interface down so that other code can target it. However, internally there is just a "convert" function. Eventually we should rework the code itself to use the composition module more directly.
