* platform image providers * use key * fix cache manager * more logs, cancel on dispose instead * split into separate files * fix saving to cache * cancel multi-stage provider * refactored `getInitialImage` * only wait for disposal for full images * cached image works * formatting * lower asset viewer ram usage --------- Co-authored-by: Alex <alex.tran1502@gmail.com>
