[Feature Request] Use url-retrieve to fetch weather info

[condy0919]

No requirement of curl, so it can run on windows out of box.

Hello Condy0919,

If we would to drop the curl dependency, the capability to fetch multiple cities like this https://wttr.in/{Nuremberg,Hamburg,Berlin}?format=3 will be lost since url-retrieve fetches info as a browser.

Unless we manage fetching multiple cities ourselves; consequently making multiple requests.

I will be taking a look into it.

(dolist (city '("Nuremberg" "Hamburg" "Berlin"))
  (url-retrieve (format "https://wttr.in/%s?format=3" city)
                (lambda (_status)
                  (let ((buf (current-buffer))
                        (end (1+ url-http-end-of-headers)))
                    (with-temp-buffer
                      (insert-buffer-substring buf end)
                      (decode-coding-region (point-min) (point-max) 'utf-8)
                      (message "%s" (buffer-string)))))))

Since url-retrieve is async, it can be done in a loop. The same as curl does.

I created a new pull request removing the curl dependency. Would you like to test it before a merge to main?

It works, thanks.
