Took in-lock charge measurements at 21:19UTC

As they've been skipped the last few weeks 75271, today while ISC_LOCK was in OMC_WHITENING waiting for violins, we took in-lock charge measurements. 21:19UTC to 21:35UTC.

There was a glitch at 21:33:10UTC at the end of the ETMX injections/ transition, should check if that's due to a mistake in the code.

Glitch at  21:33:08.36 UTC is when ESD_EXC_ETMX changes H1:SUS-ETMX_L3_DRIVEALIGN_L2L from DECIMATION, OUTPUT to INPUT, DECIMATION, FM4, FM5, OUTPUT. This confused me as the gain was zero at the time but 2 seconds before, gain was changed from 1 to zero at the same time the tramp was increased to 20s, meaning the gain wasn't really zero.  I've added a 2 second sleep between the gain change to zero and the tramp increase to avoid this in future and reloaded.
