A reference-counted byte buffer.

ArcBytes is a type that is useful when parsing a buffer of bytes and breaking it into smaller pieces without extra allocations or extending the lifetime of the underlying buffer. This is done with no unsafe code by leveraging std::sync::Arc. When the final reference of the buffer goes away, the underlying bytes will be released.

This type also implements std::io::Read and std::iter::Iterator for easier integration with existing code.

With the feature flag serde enabled, serde::Serialize/serde::Deserialize are implemented in such a way that ensures the bytes are written optimally and not as a sequence of u8s. This is almost identical to the approach that serde_bytes utilizes, except ArcBytes uses a single type and introduces the use of Arc.
