Feature/add supercluster visualization

[ebefarooqui]

This is a preliminary PR to get feedback for the supercluster visualization. Currently, the styles are still in question (opacity, size of cluster, cluster radius) and we will be reviewing different styles soon to gauge what is best for the user.

See comment below for more updated information

Love this feature. Do you want general comments regarding what's missing and bugs, or just inline comments on the code reviewing what you've done so far?

Really excellent work/feature! I've made a couple of structural suggestions around code quality. I haven't been able to test the feature yet in a browser, due to having the wrong config I think (have sent you a message privately).

This extraRender logic is a good candidate for making into a HOC now, I think, given that it's used both here and in Events.jsx.

This PR should be fully ready to review. I've attached the appropriate timemap config file here.

Note that the categories are currently broken on this branch, but you shouldn't need to test with them anyways. The styling for the clusters (opacity, size, cluster radius) are the ones decided on in the chat, but any and all suggestions welcome.

In order to run locally with updated data, I created a test_export_events tab in the datasheet, so in order to see the data locally, make sure that the return statement in src/lib.js in ds-s looks like the following:

return {
[test_export_events]: BP.deeprows,
[${prf('categories')}export_categories]: [BP.groups, BP.rows],
[${prf('associations')}export_associations]: BP.deeprows,
[${prf('sources')}export_sources]: BP.deepids,
[${prf('sites')}export_sites]: BP.rows
}
