[Rnomads-user] failed to load external entity

[Daniel Bowman]

Hello Wouter,

NOAA is changing from the http to https protocol, and while I thought
I had fixed that, it looks rNOMADS is still trying to access DODS
archives using http.  I'll fix this shortly and release a new version,
and I'll let you know when it is available.  Sorry for the
inconvenience!

Best,

Danny
