Fix olc-decode and geopoint latitude and longitude order in the geospatial plugin (#8437)
* Reverse latitude and longitude in olc-decode tests to match proper geojson output format

* Reverse latitude and longitude in olc-decode to match proper geojson output format

* Reverse latitude and longitude in geopoint expected results to match proper geojson format

* Reverse latitude and longitude in geolookup expected results to match proper geojson format

* Corrected the Oxford to New York distances

* Oxford is actually 12 miles closer to New York than Winchester

Used calculator at https://www.nhc.noaa.gov/gccalc.shtml to check

Reversed latitude and longitude to correct the geojson

* Reversed the latitude and longitude turf.point arguments in the geopoint function

* Swapped latitude and longitude in geopoint function calls
