Can now provide reference iostore containers to reuse compressed chunks from. If a match is found on *the decompressed data*, instead of recompressing the blocks, they are read off of disk. This allows tweaks of the compressor algorithm without introducing changes as the runtime still sees the exact same data. Additionally this allows for fairly dramatic staging speedups as nvme speeds are significantly faster than high effort compressions. This is distinct from the DDC compression because:
1) DDC compression ties in the compressor version/method
2) We are explicitly interested in chunks that are deployed to end users, not merely cached for speed.
To facilitate this, several changes were made to IoStore:
FIoStoreReader now directly reads from IFileHandles* instead of routing through the GenericPlatformFile async read system, as that system is sensitive to build #defines and can result in constant file opens under load (indeed, for anything not a .pak file, every read is an open/close).
Cold file cache read speed improvements from ~140MB/s to ~1 GB/s. Hot is more.
Additionally:
FIoStoreReader switched to UE::Tasks from taskgraph for tasks in order to facilitate task retraction during waits as the previous ReadAsync call was trivial to deadlock when called from worker threads due to its use of TFuture<>.
FIoStoreReader::ReadCompressed now returns the compressed blocks as they were on disk - padded to AES encryption block size.
