Rather than using bytes.NewBuffer, which is a read/write entity (io.ReadWriter), use bytes.NewReader which is only a read entitiy (io.Reader) in all cases where it is possible. Benchmarking shows it's slightly faster and it's also technically more accurate since it ensures the data is read-only. There are a few cases where bytes.NewBuffer must still be used since a buffer with a known length is required for those instances.
