qoi-fast

VERY fast encoder/decoder for QOI image format, implemented in pure Rust.

Quick summary:

• One of the fastest QOI encoders/decoders out there.
• Compliant with the latest QOI format specification.
• Zero unsafe code.
• Supports decoding from / encoding to std::io streams directly.
• Roundtrip-tested vs the reference C implementation; fuzz-tested.
