invalid GeoJSON

[mps9506]

Returning simple features is causing problems:

> x <- echoAirGetFacilityInfo(xmin = '-96.407563',
+                        ymin = '30.554395',
+                        xmax = '-96.25947',
+                        ymax = '30.751984',
+                        output = 'sf')

There was a server error, try again later.

Fixed so this doesn't return an error. However, neither the caa or cwa webservices appear to return anything when using the get_geojson end points. I am assuming this is on the ECHO end and not a problem with the query because it appears to be broken when manually testing: https://echo.epa.gov/tools/web-services/facility-search-water#/Facility%20Information/get_cwa_rest_services_get_geojson

Appears to be working again. Need to update readme/vignette
