reference feature finder process

As more folks are starting to come on board, they are going to need an "easy" way to identify which reference features to use. For NHDPlusV2 comids/reachcodes, the NLDI point lookup endpoint may be suitable. For cataloging features, mainstems, and reference gages, some kind of other lookup will be necessary.

One option is to have a web map, similar to the shiny app. But this requires a lot of manual looking around for each and every feature of interest. Another option I was thinking would be to have a pygeoapi process running on reference.geoconnex.us, where you could programmatically supply a lat/lon, and get a response of the members of every reference collection within a small bbox of the supplied lat/long.

e.g.

https://reference.geoconnex.us/processes/lookup?lon=x&lat=y

might return something like:

{
    "gages": [
        "https://geoconnex.us/ref/gages/1073686",
        "https://geoconnex.us/ref/gages/1185820"
    ],
    "mainstems": "https://geoconnex.us/ref/mainstems/2600",
    "hu10": "https://geoconnex.us/ref/hu10/1802011101",
    "counties": "https://geoconnex.us/ref/counties/06061"

}

We could even possible have a https://reference.geoconnex.us/processes/lookup/map?lon=x&lat=y that would give you something like this
