[Stefan, Jenne]

Earlier in the day, we were struggling to get through the INCREASE_POWER state in the ISC guardian, which happens after the transition of DARM to DC readout.  

After much tracking and searching, we discovered that the problem was that the setpoint for the OMC transmitted power was done as an ezcaread after the PSL rotation stage had already started moving.  Stefan had seen in the past that this kind of system will often have some lag (you're not reading the current OMC DC PD value infinitely fast, so you're constantly changing your setpoint) which causes the system to run away.  

We have changed this to a hard-coded value (defined as lscparams.omc_dcpd_sum_target), so that the DARM offset is changed while the power is increased to keep the OMC DC PD at this value (currently 20 mW).

This seems to now work exactly as we expect, and we're easily able to get past this state.
