Add support for exiftran

[Rodolfo]

Describe your feature request
When media is captured by a camera it includes the orientation tag, which is the way cameras tell computers how to display the image for us. In Chevereto we have an orientation fix, which normalize the orientation of the media and ease handling for it. Unfortunately, this process is destructive as it needs to re-build the image.

This suggestion is for adding support for exiftran which is a tool that will enable to perform lossless JPEG transformations, we will be able to rotate images and keep the pixels "as-is".

Where did you see this?
Anytime when you upload a picture taken sideways Chevereto will re-generate that image.

Yes, there's a bug report and that's enough around here.

Thanks Rodolfo. This should make uploading faster, no? Anyways, sounds great to me.

This aims to make the image orientation process lossless for JPEG. The problem we have now is that when you take a picture sideways and upload it to Chevereto, the system will orient the image using Imagick/GD which re-build the bitmap, causing a quality loss. This is often not perceived by users, but in the context of high-quality imaginary this is a must have.

With exiftran we will get lossless image orientation fix, meaning that the pixels will remain "as-is", without altering the quality of the media being uploaded.

And yes, way faster than Imagick/GD to orientate the image.
