ProPlus 2.1 Temperature Values

[Sam Calhoun]

Hi,

Just writing to say that after using libdivecomputer in my program and 
testing it with a few different devices, I have found one small bug.  
The ProPlus 2.1 (the version with metal buttons) did not parse 
temperature values correctly.  Here's the small change to 
"oceanic_atom2_parser.c" that fixed the issue for me (relative to the 
latest snapshot on the download page):
