`find_stations`

returns a tibble with the nearest stations'
distances using a given point's longitude and latitude values. This function
uses the Haversine formula for distance calculation in km.

1 | ```
find_stations(longitude = 24, latitude = 38)
``` |

`longitude` |
a numeric value in degrees |

`latitude` |
a numeric value in degrees |

If the given longitude is in [24, 38] and the latitude is in [34, 42] (i.e. are valid values for Greece) returns an ordered tibble with the station_id, name, subdomain and distance values in km. The station's data that are used come from the 'stations' dataset. Otherwise returns an error message.

# find the five nearest stations to a point near Thessaloniki,
# (lon, lat) = (22.97, 40.60)
head(find_stations(22.97, 40.60), 5)
