- Use `Fprintf` to convert to hex and do padding. Simplifies the code. - Use `Read()` and `io.ReadFull` instead of `ReadByte()`. Should improve performance and allows for cleaner code. - s/pktLineTypeUnknow/pktLineTypeUnknown. - Disallow empty Pkt line per the specification. - Disallow too large Pkt line per the specification. - Add unit tests.
