add ncl dewtemp_trh outputs

[cyschneck]

Adds dewtemp_trh output values to use for dewtemp in applications (NCAR/geocat-applications#100)

It looks like it's fairly easy to programmatically generate and check inputs / outputs for this function. Can this be thinned down a bit and live in GeoCAT applications? I feel like that's what we did for some of the other functions.

Totally possible I missed something here too (apparently I did).

Outside of the conversation on location that I'll leave to our slack conversation, I have a small suggestion. Assuming it would be minimal effort, I think it might be useful to include the corresponding inputs in the file as additional columns. As in, outputting columns of temp, rh, and then the calculated dewtemp. This would make it easier to recreate and compare over in geocat-applications, as well.

Also, the ncl script itself should live over in geocat-applications.

Removed dewtemp_trh.ncl and included the tk/rh as values in a comma separated columns with dewtemp

registry file needs an update, but otherwise looks good.
