[idvusers] NOAA ESRL THREDDS Catalog URL (http --> https)

Dear IDV Community,

We have received a few support requests concerning the THREDDS catalog at

http://www.esrl.noaa.gov/psd/thredds/catalog.xml

The problem is NOAA recently switched to https so simply replace http with
https:

https://www.esrl.noaa.gov/psd/thredds/catalog.xml
