v0.5-beta MacOSX stability fixes and new audio command

Known issue: Linux support seems to be a bit flaky so I will look at how to improve that next.

• Added new Debian Dockerfiles for building and running the tool inside Docker easily

• I fixed MAC OSX stability issues and the tool should now work without unplugging the device every time and without starting the tool multiple times.

• It now works with multiple devices

• I added the new audio command to record only audio without changing the status bar of the device

• Now builds with go 1.15 and dependencies have been updated

Add working Gstreamer for AV Playback

This release includes the gstreamer command which will open up a desktop window with audio and video playback of any iOS device connected. It works on Linux and Mac OS X.

Known Issues:

• On Linux: the device needs to be unplugged after a session for the tool to work a second time
• On Mac OS: after a session, start the command ignore the error, wait 10 seconds, start the tool again and it should work
• Sometimes the lengthfieldbased decoder fails with some weird data received from the device, i think it is
  safe to ignore but currently the program will exit
