Requiring the use of a separate reader type makes it more likely that readers will be reused, and makes it easier to audit reader usage going forward. Reusing readers is desirable to reduce the number of large temporary allocations made during partial decompression of a buffer.
- Added FCompressedBuffer::Save(FArchive&) and renamed FromCompressed(FArchive&) to Load(FArchive&).
- Added FCompressedBufferReaderSourceScope to set a buffer source within a scope.
- Added proper bounds checks to FNoneDecoder.
- Store the header checksum on the decoder context to allow raw blocks to be reused across sources.
- Decode the header on the fly to avoid a temporary header allocation when the header is in contiguous memory.
