Add toggle for flags on maps in Umbrella Projects

In umbrella projects the project author can decided whether to have flags on the map indicating areas or not to have them shown. These flags can be useful for identifying specific areas within the umbrella project but as lower zoom levels they can become chaotic as they overlap and make viewing the map very difficult.

Could the map on umbrella projects have a clickable button so that the user/viewer can turn on and off the flags (for their own single viewing session only) and thereby make the map more viewable at lower resolutions but be able to bring the flags back into view for viewing further information ??

Many thanks.

Platform(s), such as mobile, website, API, other:

URLs (aka web addresses) of any pages, if relevant:

Description of need:
Describe the iNaturalist community need that your requested feature addresses. Include screenshots, URLs, and other details to help us all understand the issue.

Feature request details:
In detail, describe the feature you are requesting. This includes its functionality, where the feature is implemented, and what it might look like. Screenshots or mock-ups are helpful. The idea is to have a concrete and actionable request which the community can discuss and vote on. It might change through discussion, but it’s much easier to iterate and talk about something specific.
