TinyRGB support for JPG thumbnails

TinyRGB support for JPG thumbnails

TinyRGB is an ICC profile released by Facebook under CC0.
It is designed to be fully compatible with sRGB.
It offers the vast advantages of being much smaller than sRGB,
as well as being free as in freedom (the sRGB profile found in the
majority of JPGs is copyrighted).

This change aims to provide the ability to swap sRGB for TinyRGB at
the time thumbnails are generated.

JPGs that use another ICC profile than sRGB or no profile at all are
unaffected.
