Expand description

Recognizes an unsigned 1 byte integer.

Streaming version: Will return `Err(nom::Err::Incomplete(_))` if there is not enough data.

    use nom::number::streaming::le_u8;

    let parser = le_u8::<_, (_, ErrorKind)>;

    assert_eq!(parser(&b"\x00\x01abcd"[..]), Ok((&b"\x01abcd"[..], 0x00)));
    assert_eq!(parser(&b""[..]), Err(Err::Incomplete(Needed::new(1))));
