Include zstd compression & decompression in serde

[CompeyDev]

Closes #202.

Looks good so far! Just the tests failing, does the zstd cli need some args changed maybe?

Was the formatting here changed on accident? This file should definitely be less than 80 wide (prettiers default) and not have to wrap across lines

[CompeyDev]

Yeah, that must've been what happened - I ran prettier on root and it didn't respect the config perhaps?

I've tried most permutations of the arguments that I can pass to the CLI - async-compression's best mode corresponds on ZSTD's MAX_CLEVEL, which is 22 (I've read the source of both the crate and zstd to confirm this).

Did you figure out what could be going on here? Not really sure myself but I also haven't looked too deeply into it.

Unfortunately no :( Others in the lune channel could not figure it out either.

According to the zstd CLI tool (downloaded from the zstd repo) the best compression level is 19. Are we sure that 22 is the max it uses?

between 1 and 19; << In normal mode
They provide '--ultra' extra option (Enable levels beyond 19, up to 22; requires more memory.)
Steps 20 and above work a little differently and are slower
