Summary: Use NSData as key Add chunking of files Add support for Animated Images This adds support for GIF playback in ASDK. It's not currently ready for merging to public ASDK – for one the GIF decompression may make more sense in PINRemoteImage. Removed duration as it wasn't used Make cover image lazily loaded Differential Revision: https://phabricator.pinadmin.com/D82033
