secrecy vs redactedsecret vs zeroize

Wrapper types and traits for secret management which help ensure they aren't accidentally copied, logged, or otherwise exposed (as much as possible), and also ensure secrets are securely wiped from memory when dropped.

This is a fork of the official Secrecy crate [https://github.com/iqlusioninc/crates/] Wrapper types and traits for secret management which help ensure they aren't accidentally copied, logged, or otherwise exposed (as much as possible), and also ensure secrets are securely wiped from memory when dropped.

Securely clear secrets from memory with a simple trait built on stable Rust primitives which guarantee memory is zeroed using an operation will not be 'optimized away' by the compiler. Uses a portable pure Rust implementation that works everywhere, even WASM!
