magic: Add MagicPacket.send_to method 

On the off chance that the magic packet needs to be sent to a
destination other than port 9 on the subnet-directed broadcast address,
the `send_to` method is now available on the `MagicPacket` structure.
The `send` method is retained, and now simply delegates to the `send_to`
method with a hard-coded socket address.
