About the freeverb crate

This implementation of Freeverb in Rust is an almost direct conversion of the original source, created as a demonstration project for a talk Ian Hobson gave about Rust at the Audio Developer Conference 2018.

There are a couple of (intentional) differences to the original implementation:

• Delay line buffers are dynamically allocated for simplicity. This may have a performance impact; making the buffer static with generic constants is an alternative.
• 64 bit processing is used internally whereas the original is 32 bit. Making the sample type configurable is an option.
