Example in README file does not work, cannot find encode/decode in this scope

encode and decode have changed to encode_slice and decode_slice since 1e6d843

The following changes to the example work for me:

use bytes::BytesMut;
use mqttrs::*;

fn main() {
    // Allocate write buffer.
    let mut buf = [0u8; 1024];

    // Encode an MQTT Connect packet.
    let pkt = Packet::Connect(Connect {
        protocol: Protocol::MQTT311,
        keep_alive: 30,
        client_id: "doc_client".into(),
        clean_session: true,
        last_will: None,
        username: None,
        password: None,
    });
    let encoded = encode_slice(&pkt, &mut buf);
    assert!(encoded.is_ok());
    let mut buf = BytesMut::from(&buf[..encoded.unwrap()]);

    assert_eq!(&buf[14..], "doc_client".as_bytes());

    // Decode one packet. The buffer will advance to the next packet.
    assert_eq!(Ok(Some(pkt)), decode_slice(&mut buf));

    // Example decode failures.
    let mut incomplete = buf.split_to(10);
    assert_eq!(Ok(None), decode_slice(&mut incomplete));
    let mut garbage = BytesMut::from(&[0u8, 0, 0, 0] as &[u8]);
    assert_eq!(Err(Error::InvalidHeader), decode_slice(&mut garbage));
}

I suggest updating README.md with this, if the repository owner is ok with this

In addition, I'll be forking the repository to try and work in some MQTTv5 features as I have a need for some of them (mainly Message Expiry and Maximum Packet Size)
