Clarify accepted spatial data file formats in documentation

[adricaswell]

Only shapefiles can be input into the Spatial Data Analysis portion of the app. Keyhole Markup Language (kmz), Geographic Markup Language (gml), and GeoPackage (gpkg) file formats were tested and do not appear as options when choosing files for Spatial Data Analysis. Make sure it is clear in the documentation that geospatial data must be in the form of a shapefile.

Also look into what it would take to support more formats

[adricaswell]

Change “physiological thermal niche file” in the Spatial Data Analysis tab to “physiological thermal niche shapefile” to indicate only shapefiles can be input.

This needs to be done more clearly. Probably in popups for details beside each spatial input file.
One user said: "originally had made .tiff files, which the app doesn’t recognize. When I converted those to .tif files, it also didn’t work as I discovered there are two kinds of .tif files, regular and GeoTifs. If you could make it clear that you need GeoTifs in the .tif format, that would be useful."

Also had confusion with the multiple files that are needed for a shapefile to work.
