DATE-OBS issue in dar.py - SUPER-EASY FIX

[cdfassnacht]

Hi, I recently got an error while reducing data, where the code crashed because the DATE-OBS header key wasn't in the expected format. See the traceback below. While I don't know if adding the time to the DATE-OBS value, via the "Thh:mm:ss.s" added to the end of the string is fits standard, I have definitely seen this format several times. The fix is a super-simple change to dar.py - in line 324 in the version on the dev branch or line 325 in the version on the main branch:
Just change day = int(date[2]) ---> day = int(date[2][:2])
I've done this in my local version of KAI, but since the change is so quick, you can probably put it in the distributed version without any trouble.
