Experiment with Backend Sleep time

[Allstreamer]

• Reduce sleep time?
• Introduce random offset?

Motivation:

• Reducing the sleep time between request checks will increase the speed at which requests can be served.
• Introducing a random offset to the sleep timer may prevent a (albeit very unlikely) deadlock, in which the GUI and Backend sync up to perfectly block one another. The randomness would mean that the lock would resolve itself eventually. Although this may not be necessary as egui by default does not render at a fixed frame rate but rather as necessary, but then again this may be changed in the future so it's still something to think about.
