* WIP remove failure from all `Cargo.toml` * WIP remove `extern crate failure_derive` * Use `thiserror` to fix all errors * StoreErr is still a tuple * Remove another set of unnecessary `.into()`s * update fuzz tests * update pool/fuzz dependencies in cargo.lock * small changes based on feedback Co-authored-by: trevyn <trevyn-git@protonmail.com>
