For this change, can you add 2 page parameters that will allow people to filter the results shown by the population of the objects.

Steps

• Add to PageParamTypes PopulationLowerLimit and PopulationUpperLimit
• Add 2 Selectors (Can use LimitSelector as a template)
• Add to filtering logic (probably filter.ts but we're making some changes to this so it may look different when you get started)

You can follow this PR to see how a filter is usually added: #397

For now, just make it as 2 basic selectors, like the current LimitSelector.

Ultimately we want something fancier, like the screenshot below from the design. However, this will require more data & design work, so we'll reserve that for later.
