Lat Lng to Floats

Lat Lng inputs can be tested for being floats in case their datatype is a string:

try:
   lat = float(lat)
except:
   pass

Add more Parameters

Would be nice to include more parameters like direction & elevation

• Exif.GPSInfo.GPSImgDirection
• Exif.GPSInfo.GPSImgDirectionRef
• Exif.GPSInfo.GPSAltitude
• Exif.GPSInfo.GPSAltitudeRef

Keep up the great work!

I'll send a fork once I have time to include these.
