Handling multiple polygons in a single request

[zacharyDez]

@andresfchamorro raised the possibility of submitting a post requests with multiple different aoi such as specific regions/districts within a country. He mentioned conserving the id, and properties of the geometry (aoi) in the resulting response.

@andresfchamorro was the use case specifically working from a dataframe where each row is an entity with its own geometry or was there another use case in mind?

@vincentsarago any thoughts design to support multiple polygons?

@zacharyDez, I guess we will replicate what we do in titiler https://github.com/developmentseed/titiler/blob/main/src/titiler/core/titiler/core/factory.py#L471-L525

Based on a discussion with @andresfchamorro and @bpstewar, we will, at least initially, let users make multiple requests for multiple polygons of interest (aoi) and figure out how to merge/manage multiple data frames on their own. This need may emerge shortly, but we are punting a lot of complexity that may be needed. For example, how should we manage polygons that overlap and return duplicate h3 identifiers?
