Present benchmarking results in documentation

[tp832944]

What's the new feature?

In #509, we will commit fairly thorough benchmarking data. Make this accessible to casual browsers of the documentation. Write a page giving guidance on each coreset algorithm, their speed and other merits/disadvantages, and which to try in each situation.

What value does this add?

Help people to use and engage with Coreax.

Is there an alternative you've considered?
