ManagedStream: low fps when there are more than two clients

#12 might be why

TL;DR: The more tabs you open, the lower fps the stream gets.

Went back to 1c56c86 but couldn't reproduce the issue. It might have been caused by a dependency. I probably should pin the dependencies. note to myself

An old/bad camera also causes this

This is also related to FPS. If fps is set high too high, the stream handler is called too many times.

If the FPS is set to 60 and we have 5 clients open, then: 60*5=300 calls per second. Even though calls after 60 don't trigger a frame reading and processing, that's still a lot of calls I believe.

I think I need someone more experienced for this one.

About the bad cameras: I think the problem is the combination of both too many calls and the camera's bad shutter speed. So even if the camera is 30 fps you have to set a very low exposure to work correctly.
