Dark offset for OMC DCPD

Adjusted the dark offset of OMC DCPDs in A0 and B0 filters and zero-ed A and B offsets (and disabled them).

  H1:OMC-DCPD_A0_OFFSET A_OFFSET B0_OFFSET B_OFFSET
Old -158 68e-6 -134 -803e-6
New -81.6 0 -89.5 0

I don't know exactly why people split these offsets in two different places, maybe that's because dark offset scripts was written when 512k ADC didn't exist?

Let's use A0 and B0 offsets for ADC rather than putting ridiculously small numbers in A and B.
