Consider using snappy along with snappyjs

Is your feature request related to a problem? Please describe.

Right now we only use snappyjs and it's good with current gossip message size, but after the merge the block size is way bigger and it's better to use "snappy" at least for beacon_block topic, it also support async version

• The benchmark: https://github.com/ChainSafe/lodestar/blob/tuyen/benchmark-snappy/packages/lodestar/test/perf/network/gossip/encoding.test.ts#L33
• The result

Uncompressed size	Times of attestation size	# of runs per second - snappyjs	# of runs per second - snappy
229 bytes	1	815	120
22.9 kb	100	2022	2047
114 kb	500	3.6	8.6

Describe the solution you'd like

Consider using snappy for beacon_block topic and snappyjs for other topics

another direction is to research if we can port the snappyjs implementation into assembly script since the interface is similar to as-sha256

Reevaluate snappy locations based on current block sizes.
