Dedicated widget for seed control

[quaquel]

As discussed in #2496, having a clean dedicated widget for seed control would be nice. This should allow for controlling the seed and falling back on None (so fully random) if desired.

can I take this issue?

@nissu99 Yes. Two things to watch out for:

• Add Interactive Play Interval Control to Mesa Visualization #2540 is touching the same part of the codebase, which could be cause a merge conflict if you also open a PR. You can either watch till that one is merged, or resolve the conflict when it happens.
• We need to agree on an API / user interface. My proposal is that this seed widget is enabled by default for all SolaraViz models, but I think there were some different ideas on this.

sorry for acting late on this issue ,my exams just got over.

@EwoutH do we also need a component to track the seed state,read discussion from @quaquel in #2496 regarding this.

[EwoutH]

No worries, hope they went well!

I don't think seed state tracking is required at this moment, but I will also let @quaquel pitch in.

[quaquel]

I would like to have it back at some point, but there is no rush.

how does this look --

seed when set random

seed changed manually

@quaquel @EwoutH @Corvince how is this checkbox type design?

[EwoutH]

Design wise I think this is nice, @quaquel any comments? Do we want/need to support seeds other than integers?
