Bugfix/raw input space

[alexdhill]

Description

Added raw flag to image model (TaggedImage) to enable easier to manage parsing of image color spaces.

There has been a lot of discussion about the performance and quality of the RAW image color balancing and auto adjustments - some of which I believe is due to the fact certain fns didn't seem to account for the RAW colors (panorama/auto adjust/etc.). I have made some slight patches to account for this - and added some alternative auto-adjustment modes which perform much better in certain scenarios. For consistency, default behaviors have not changed.

When selecting the auto-adjust it acts just as before, but holding on the button will allow you to select other adjustment algorithms (Geometric Mean and Zonal correction). I found zonal works pretty well but performance will likely be dependent on the image itself.
