evas_generic_loader: Add raw image format loader. There are dozens of raw photo formats: CRW, CR2, MRW, NEF, RAF, etc. 'RAW Format' does not exist; it is an illusion created by dcraw's ability to read all raw formats. So I use libraw who was nearest of dcraw. So we have more formats supported (foveon) and better rendering (default icc profile from camera) as libopenraw provides. shm_file seems doesn't work if someone want to fix it... I'm on
