Feature to not use unsafe

[dcormier]

I would gladly accept a performance penalty in exchange for not using unsafe code. If there were a feature on this crate to allow that tradeoff, I would use it. As it stands, I cannot use this library because of the use of unsafe.

Done! Just released version 0.2.0 with 100% safe Rust code.
Thanks once again for your constructive feedback.

Great, thank you! Now you could even add #[forbid(unsafe_code)] to lib.rs to make it more explicit that the crate is not using unsafe code.

Perfect, thanks!
