Sleep Guard

[Tyr3al]

I had the problem, that av1an encodes would not run through overnight, as my system would simply go into sleep - even though an encoding job was already running. In my case that would be Arch Linux. It seems like other people have this issue as well, see #889.

This PR ads a sleep guard to av1an that should prevent sleeping while an encode is running. I first tried to use the suggested crate keepawake as suggested in the Issue, but it pulled far more dependencies as expected, which were also outdated.

I sat down to write implementations for linux, windows and macOS myself, that should prevent the system from going into sleep.

I have tested the linux and the windows implementations. The macOS implementation is untested, as I was not able to get av1an to start an encoding job there.

Thanks for your PR!

This seems important but can't you handle it on the OS level instead with much less complexity?

And screen locking would be a needed functionality while it runs.

AFAIK, there are some things you can do outside of the application to prevent sleep. This PR is rather a convenience function, so that you do not have to call av1an from another wrapper. E.g. in linux:

systemd-inhibit --why="Prevent sleep during execution" --what=sleep ./av1an

And screen locking would be a needed functionality while it runs.

The screenshot may be misleading. The sleep inhibitors I'm creating only prevent sleep. The system is still able to turn off and lock the screens.
