[FEAT] Seed for comparison_viewer_dashboard?

[zmbc]

Is your proposal related to a problem?

In a computational pipeline that uses Splink, the output of the comparison_viewer_dashboard changes each time it is run.

Describe the solution you'd like

I'd like to be able to pass a seed to comparison_viewer_dashboard that results in the same dashboard being generated every time. I think the only part that is random is the choosing of rows as examples.

Describe alternatives you've considered
