TWP/SKYRAD/C2 - PIR offline for B/W comparison

The shaded PIR was disconnected so a side by side comparison could be made with the shaded 
PSP and new shaded B/W PSP.

• PIR shaded standard deviation(pirs_sd)
• PIR shaded minimum(pirs_min)
• PIR shaded maximum(pirs_max)
• PIR shaded mean(pirs_mean)
