ENH: include new ics vlans

[ZLLentz]

For reviewers: I'm mostly looking for a sanity check that these additional VLANs match reality.

The first commit here is a hotfix because Russ wanted to use the switchtool to set up some mfx-ics devices. Afterwards, I queried for the rest of the VLAN infos.

Then, I did the following:

• Paste in Omar's list from https://jira.slac.stanford.edu/browse/ECS-4375
• Fix small typos
• Coerce into json format

I realize that the sorting of this file is really odd but I left it this way on purpose so it'd be easy to review. I'm all ears for suggestions on the best way to sort this, sorting by VLAN number and sorting by subnet name both feel strange to me.

Copy of Omar's comment from the Jira:

621 ics-abl.pcdns
613 ics-cxi.pcdsn
608 ics-det.pcdsn
620 ics-las.pcdsn
615 ics-mec.pcdsn
649 ics-mfx.pcdsn
631 ics-rix.pcdsn
644 ics-tmo.pcdsn
619 ics-txi-pcdsn
617 ics-ued.pcdsn
614 ics-xcs.pcdsn
647 ics-xpp.pcsn

This seems like it matches omar's list, though I'm a bit unsure how to best check all of these

[tangkong]

This -pcdsn is intentional but the sn <-> ns swaps are not? I realize it should be pcds, but what's the proper way to check these against our system? Are these just arbitrary names that we get to use or are they checked against some table?

I missed this one, will fix typo

This looks good to me, from what I could see comparing to the ticket
