Closes WP 12577.

The running code is now at commit 0faf5c4aeb5c61116a5abf0573cb3d09ffdc9e7c in https://git.ligo.org/cds/ifo/beckhoff/lho-vacuum.

This completes the remaining part of the work permit:
"Update the PLC code on h0vacly to pull and use the following changes from git: "Changed the names of the IP23, IP24, and IP25 filter cavity ion pump controllers. Added IPFCC6 and IPFCC8 filter cavity ion pump controllers. Commented out IPFCC6 and IPFCC8. Commented out PT100 as a Pirani and Cold Cathode gauge pair."

After regenerating the TwinCAT 3 solution and running a scan for devices it showed that Box 1, Box 4, PT154 and PT157 had different hardware revisions than they were configured for in the solution. I changed the PowerShell script to make them match, but when I ran it I found that the device driver installed for these gauges did not match the new revision number. I looked on the MKS website for updated drivers, but could not find any drivers at all. I looked back through my emails and found that Chandra had given me the one I currently have, and remembered that she had probably gotten it from the manufacturer directly. The most feasible solution I could think of to do in the time remaining was to revert the revision numbers in the software and run with the mismatch. I don't see any issues at present, and apparently PT154 has been running with the mismatch since it was replaced a while back.
