Change image rename to use exiftool?

[esturdivant-usgs]

I was trying variations of this to no avail:

cmd = """exiftool -d {}_{}{}_%Y%m%dT%H%M%SZ_%%f.%%e "-filename<GPSTimeStamp" {}""".format(surveyid, cam_id, flight_id, imagefolder)
subprocess.check_call(cmd, shell=True) 

Problems:

• GPSTimeStamp does not include date so it won't be able to update the date portion of the filename.
• That command failed on Windows because filenames can't contain colons.
• I tried to fix the illegal character issue using the semi-colon trick, but couldn't get that to work.

We could do this in two lines by 1) set the CreateDate from the GPS time and date; 2) create the filename from the CreateDate:

exiftool -d 2018015FA_m01fXX_%Y%m%dT%H%M%SZ_%%f.%%e "-filename<CreateDate" 001
