+A few more decode method optimizations for consumer delivery code paths.
 
- * `Basic::Deliver.decode`: uses `getbyte` and `unpack1` for faster field extraction
- * `Basic::ConsumeOk.decode`: simplified using `getbyte` and `byteslice`
- * `Basic::Ack.decode`: uses `unpack1` and `getbyte` for compact decoding
- * `Basic::Nack.decode`: uses `unpack1` and `getbyte` for compact decoding
- * `Basic.decode_properties`: uses `getbyte` for shortstr lengths and `unpack1` throughout
