refactor: testing blob compression

Overview

WIP for testing blob compression upstream breaking changes in evstack/ev-node#2547

I don't think this can work as using zstd-sys relies on C code and C/libc toolchain which isn't available with the succinct sp1 toolchain "riscv32-succinct-zkvm". We end up with build errors:

I'm closing this for now as the branch is very stale, but this should be tested in future if ev-node implements blob compression
