ogn-decode fails to parse fanet temperature data properly

[bzed]

Here is a dump of the same packet as received from gxaircom (WALS) and ogn-rf/decode (KoGu):

Note the difference in the temperature - its about twice of the actual value, somewhere is the encoding not applied properly in the ogn decoder.

A good example are also the (non-gxaircom) weather stations around Interlaken.

seems fixed with 0.3.2
