[feature request] Make random shuffle available

[ctlong]

The shuffle flow oftentimes groups the same people together or puts the same labels with the same people. Presumably this is due to some bug/feature with the saveHistory and shuffle flow.

It would be nice if users could choose to shuffle without using history (by some random algorithm).

@ctlong Are you referring to the "recommend pairs" button? I just learned from the README that it's not really intended to shuffle, though my team was hoping that it would shuffle. It gives the same result when someone clicks it more than once. But it gives a different result when a different user clicks the button, also the same each time the same person clicks it.

I think I'm going go have to get out my dice if we want to shuffle our pairs.

Yes, I am referring to the "recommend pairs" button.

I think providing the computational equivalent of getting out dice is what a lot of folks want.. Probably with some guardrails like:

• Leaving track and role labels,
• Not removing everyone from a lane so one person retains context.
