* Reads with Decompression *
For a non-fragmented read with decompression (`flags` has `DECOMPRESS_WITH_ZSTD` set)
`dev_offset` and `length` should specify the compressed blocks. `total_compressed_bytes` should
be the total number of compressed bytes. `uncompresed_bytes` is the total number of
uncompressed bytes. `compressed_prefix_bytes` specifies the padding at the beginning before the
start of compressed data.
For a fragmented read with decompression:
For the first request in the group: `dev_offset` and `length` should specify the compressed
blocks for the first fragment. `total_compressed_bytes` should be set to the total number of
compressed bytes across all requests, and likewise for `uncompressed_bytes` and
`compressed_prefix_bytes`.
For subsequent requests, `dev_offset` and `length` should specify the compressed blocks. All
other fields should be zero.
The group may only contain read requests applicable to the decompressed read.
There is a 128 MiB limit on the total compressed amount.
