Error upon non-existing places are unintuitive

[oniichaNj]

Consider the following example;

package main

import (
	owm "github.com/briandowns/openweathermap"
	"log"
)

func main() {
	w, err := owm.NewCurrent("C", "en", "<redacted>")
	if err != nil {
		log.Fatal(err)
	}

	err = w.CurrentByName("St Petersburg")
	if err != nil {
		log.Fatal(err)
	}
	log.Printf("Temperature in %s: %.1f °C\n", w.Name, w.Main.Temp)

	err = w.CurrentByName("fff")
	if err != nil {
		log.Fatal(err)
	}
	log.Printf("Temperature in %s: %.1f °C\n", w.Name, w.Main.Temp)
}

This outputs json: cannot unmarshal string into Go struct field CurrentWeatherData.cod of type int as an error for the second CurrentByName call.
Perhaps a more descriptive error message could be used here?

The response of the particular query is 404 Not Found. Do you think we need to just map the response codes to messages?

I would think that returning the provided location with the error would provide necessary context. Would more be needed?
