Add Light Value, a calculated value, to the EXIF Camera Data

What problem do you see this solving?

Provide a useful tidbit of information to Capture One users.

Light Value represents the amount of light the camera sees from a scene and it is derived from other EXIF Camera data. It is given by: LV=log2(N**2/t)-log2(ISO/100) where N is the f-stop, t is the shutter speed in seconds and ISO is the sensor ISO value.

It similar to Exposure Value, but compensates for the ISO the camera is using. If the camera is using ISO 100, Light Value and Exposure Value are the same.
