CCR patch: Create memory space to store cylinder pressures

Browse source 
This patch creates memory space to store both the cylinder pressure of the
diluent cylinder as well as the oxygen partial pressures of up to four
oxygen sensors. This is accomplished within profile.h
1) To the plot_data structure, add:
   a) an array diluentpressure[2] to store diluent pressures
   b) create o2setpoint and o2sensor[4] to store oxygen partial pressures
2) Define a constant and prototypes to access the cylinder pressures
   and their corresponding interpolated values.
