#117 Add SADR/MAC address to 'device scan' output and allow copying of response-packet bytes

[Dennis McEnaney]

It would be great if the I-Am response output (for a 'device scan') included the "SADR"/source-address, or rather the device's MAC address (for the cases when it has indeed been set within the response-packet).

E.g. Purely for explanation, maybe something (inclusive) like the following:

Device 8350125 at 192.168.1.26:57572 on network 1. Vendor: ACME., Inc.. maxAPDU:1476. no-segmentation, source address '00-12-3A-7B-3C-1F'
object-name: "Office 6 8350125"
model-name: "ACME BACnet"
application-software-version: "2.0"
protocol-revision: 4

It would also be nice if you could (cut-n-paste) 'copy' the selected bytes within the packet-bytes display window, or at the very least, all the bytes.

(Great tool otherwise! ;D)
