Update package name and hash Add compressor names. Update ImageProcessingAtom unit tests. Removed some unused test assets under ImageProcessingAtom Enalbe ISPC to all the platforms. Better error message with compression/decompression Add temp folder to git ignore added ispccompressor for all platform. valid it with linux Update windows package hashes. Removed AZ_TRAIT_IMAGEPROCESSING_USE_ISPC_TEXTURE_COMPRESSOR Minor refactor with image processing unit tests. Signed-off-by: qingtao <qingtao@amazon.com>
