Py3 cmon.py and exfoliation station.html.tmpl updates/changes

[tut...@gmail.com]

Hi,

With the update to Py3 version of weewx, I ran into a failure to execute the cmon.py unless I made this change to the file:

327c327
<             p = Popen(cmd, shell=True, text=True, stdout=PIPE)
---
>             p = Popen(cmd, shell=True, stdout=PIPE)

otherwise cmon would exit on a compare type mismatch

Also for Raspbian OS latest update the cpu temp file seems to have moved to

/sys/class/hwmon/hwmon0

and the file is temp1_input , needed to tweak the station.html.tmpl in exfoliation to add cpu_temp1 for graphing.
