Azz Re-Optimization

Using the Bosted code, which now uses the complete cross-section with both QE and DIS parts, has been checked against previous data, and uses the full dilution factor, I've gone back through beam energies of 6.6, 4.4, and 2.2 GeV and optimized the physics rates while keeping the total rates below the DAQ maximum (without prescales) of 3kHz.
