pppp capture-video should have timeout if no data is coming from the printer

[kivinen]

Describe the bug

When I run

python3 ankerctl.py -p 1 pppp capture-video -m 1m output.mp4

and the printer is offline, or not in same network than the ankerctl, the command should time out after suitable timeout.

To Reproduce

Turn off the printer run

python3 ankerctl.py pppp capture-video -m 1m output.mp4

and notice that it will never timeout.

Expected behavior

It should time out after a minute or so, perhaps there should be option to specify the timeouts (perhaps even generic ankerctl top level option, or separate option for pppp capture-video).
