OPLEV charge measurements, ETMX, ETMY

* Not a great measurement, low coherence and large error bars*

I took the OPLEV charge measurements for ETMX and ETMY this afternoon. There were more overflows than typical on both ETMs during the measurements, ground motion was also elevated due to highish (~20mph) winds.

ETMX's charge is close to +/- 50 [V] on all DOF, ETMY's charge is under +/-50[V] on most DOFs except for UL_Y, and maybe LL_P.
