- Decompressing into a reused, user-supplied output buffer (also affects `safe-decode`): can
leak the previous contents of the output buffer as part of the decompressed result.

Only the block-based API is affected: `lz4_flex::block::decompress_into` and
`lz4_flex::block::decompress_into_with_dict`. All frame APIs are unaffected.
