Support basic auth with Maplibre-gl-js for map server

[benstonezhang]

This work add support of basic auth to work of pull #1038 (Support OpenStreetMap vector tiles with Maplibre-gl-js).
To use it, admin need to fill in username and password in format "user:password" in "Additional Settings" page.

The map server may use basic auth to prevent unauthorized access. Below is a example config for nginx (say martin listen on port 8080).

location /maps/ {
	auth_basic "Maps";
	auth_basic_user_file /etc/nginx/htpasswd.d/maps;

	location ~ /maps/fonts/(.*),(.*)/(.*) {
		try_files /maps/fonts/$1/$3 /maps/fonts/$2/$3 =404;
	}

	location ~ /maps/tiles/(?<fwd_path>.*) {
		include params.d/proxy_params;
		proxy_set_header	X-Rewrite-URL $uri;
		proxy_redirect		off;
		proxy_http_version	1.1;
		proxy_pass	http://127.0.0.1:8080/$fwd_path$is_args$args;
	}
}
