get MacAddr octets as fixed-size array

[jonlil]

Hello,

This is my first pull request in the Rust community. A common thing when working with network protocol e.g. UdpSocket is to compose byte slices. This new helper method provides a better interface for accessing the internal data of the mac address.

For example

Before

let mac_addr = MacAddr(0x00, 0x00, 0x00, 0x01, 0x01, 0x01);
let mut buffer = Vec::with_capacity(6);

buffer.extend_from_slice(&[mac_addr.0, mac_addr.1, mac_addr.2, mac_addr.3, mac_addr.4, mac_addr.5]);

After

let mac_addr = MacAddr(0x00, 0x00, 0x00, 0x01, 0x01, 0x01);
let mut buffer = Vec::with_capacity(6);

buffer.extend_from_slice(&mac_addr.octets());

I like it!

Thanks.

I'm sorry it took so long to get around to.
