Even though S2 typically compresses better than Snappy, decompression speed is always better.
### Concurrent Stream Decompression
For full stream decompression S2 offers a [DecodeConcurrent](https://pkg.go.dev/github.com/klauspost/compress/s2#Reader.DecodeConcurrent)
that will decode a full stream using multiple goroutines.
Example scaling, AMD Ryzen 3950X, 16 cores, decompression using `s2d -bench=3 <input>`, best of 3:
| Input | `-cpu=1` | `-cpu=2` | `-cpu=4` | `-cpu=8` | `-cpu=16` |

Scaling can be expected to be pretty linear until memory bandwidth is saturated.
For now the DecodeConcurrent can only be used for full streams without seeking or combining with regular reads.

To decode from any given uncompressed offset `(wantOffset)`:
* Iterate entries until `entry[n].UncompressedOffset > wantOffset`.
* Start decoding from `entry[n-1].CompressedOffset`.
* Discard `entry[n-1].UncompressedOffset - wantOffset` bytes from the decoded stream.
See [using indexes](https://github.com/klauspost/compress/tree/master/s2#using-indexes) for functions that perform the operations with a simpler interface.
# Format Extensions
* Frame [Stream identifier](https://github.com/google/snappy/blob/master/framing_format.txt#L68) changed from `sNaPpY` to `S2sTwO`.
