Added queue.getFps() function and tests for this function

Works (as expected). I consulted o3-mini-high and they approved it already.

The test didn't fail before, I think this introduces a race condition in the code.

How about getMessagesPerSecond instead getFPS?

[Erol444]

@SzabolcsGergely while it's more accurate, I think most people are used to FPS, even if it's actually Inference per second / Messages per second. Pehraps we could go with getQueueHz(), which is also quite widely used (aka hz == fps)?

I don't see getQueueHz fit/good choice, personally. This measurement refers to queue message rate per second.
