Description
Depending on ppv-lite86 by default makes it harder to support no_std and zeroize. Ideally we should rewrite the compressor using arch intrinsics and cpufeatures.
It also worth to implement the SerializableState trait for consistency with other crates.

Research direction
Start by locating the jh compressor and its ppv-lite86 dependency, then review how the compressor currently handles architecture-specific operations. Check the cpufeatures and no_std considerations described in the issue, along with the existing SerializableState implementations in related crates. Done means removing the default ppv-lite86 dependency, supporting the stated no_std and zeroize goals, and implementing SerializableState for jh.
