Add support for Red Sea Map

[1rfsNet]

Hello, I would like to request to add support for the Red Sea Map by Terramaps.
ProMods now lists this map as recommended map: https://promods.net/viewtopic.php?f=42&t=29618

Link to map: https://terramaps.net/download/view.php?game=red-sea
Cities JSON: cities_ut.txt

At this time the map mostly adds cities in Saudi Arabia and Egypt and these countries are already supported by local radio.

But there is one city in Sudan (Muhammad Qol). According to fmscan there is no radio channel available in this city (or whatever this is). On Google Earth, I see only a handful of houses there and otherwise forever far only nothing. And looking at this picture, I wouldn't be surprised at all. As far as I could find out, it is only a small fishing village. I would therefore skip this place altogether if there is no coverage there in reality either.
If a radio station is absolutely necessary for listening, I'll look again. Overall, however, there seem to be hardly any radio stations in the country, and since the military coup last year, even these seem to have largely ceased to exist.

It's up to the dev to integrate into the code now.
