Add udpreplay to the ADE image Dockerfile; update the Doxygen source tarball URL

Description

• For more details, see the issue which will be linked below.

Notes for Reviewer

• This MR is adding the udpreplay tool so that application developers can easily parse pcap files to emulate live UDP data

Checklist

• Documentation was updated --> Not applicable as the documentation will be added in #41 (closed)
• Once CI is finished, start ADE with this MRs images and verify that udpreplay is available within ADE
  • Locate a pcap file to test with; here's one that will be introduced to an article (#41 (closed)) soon: https://drive.google.com/open?id=1vNA009j-tsVVqSeYRCKh_G_tkJQrHvP-
  • Copy the file within the ade-home directory
  • $ ade start --select 44-add-the-udpreplay-tool-to-ade-image
  • $ ade enter
  • ade$ sudo apt update && sudo apt install tcpdump
  • ade$ udpreplay data/route_small_loop_rw-127.0.0.1.pcap
  • ade$ sudo tcpdump -i lo
    • You should see lines similar to:
