feat(compress): add lz4hc support

[tomershafir]

Summary

Add compression method LZ4HC to native writes. Decompression shouldn't be affected.

• This patch changes compress.Method actual values, as I assume clients dont depend on that.
• Feel free to reorder ch.Compression and move LZ4HC next to LZ4, based on assumption similar to the above, and rerun go generate.
