Add PSKreporter info to the map

[Fale]

Feature Description

I think it would be very useful to implement the ability to see real-time PSKreporter info on the map.
It is possible to use MQTT to retrive such info: https://www.mqtt.pskreporter.info/

What are you thinking of with this? To see where you are being heard? Or activity of other stations or what?

Sorry, I missed that part!
My personal idea is to have a map of where I'm heard (similar to https://pskreporter.info/pskmap?callsign=CALLSIGN&search=Find). Also, other possible maps/usage could be implemented easily from the same source, but might make sense to evaluate each usecase independently.

Yes, I have wanted to implement this for some time, but there is always something more important to work on.

Another point is that I would like to have this not only for PSK, but also for RBN. However, that is a separate task, and unfortunately MQTT is not available for RBN.

Another question, although this is more of an implementation detail, is how to display it on the map in a user-friendly way, since the map already contains a lot of information. Nevertheless, this is definitely a feature I would like QLog to have.

The main problem is MQTT support. Qt does not provide it, and I do not want to include another external library. Therefore, I was considering implementing it directly in the onlin-map, where an external MQTT library is available through JavaScript.
