[Dsg-hallb_magnets] Torus CERNOX board failure

[Brian Eng]

Forgot to send to mailing list, here's the results of swapping the boards out: https://logbooks.jlab.org/entry/3488318

I'm not sure what the expected accuracy/precision of the LV chassis and/or Cernox is, but it seems like a few mK difference is negligible?
