Problem in Funktion weewx_wdc.py/get_calendar_data

[Daveiano]

Discussed in #76

Hallo David,

aus bestimmten Gründen habe ich in einigen WeeWX Datenbanktabellen Zeilen mit dateTime belegt, aber den Rest der Spalten mit NULL Werten. Das ist beabsichtigt und macht bei mir für bestimmte Situationen Sinn. Es führt jedoch bei weewx-wdc zu folgendem Problem (siehe unten). Da ich von Python nicht so viel Ahnung habe, schreibe ich hier wie ich es gelöst habe und würde Dich bitten, Dir das mal anzusehen und zu bewerten, ggf. in irgendeiner Form bei Dir einzubauen.

Vielen Dank und Grüße Henry
