ADS-B station: A couple of updates to wrap up 2024

A quick ADS-B station update. A simple Python script is now responsible for collecting system vitals (RAM, storage, and CPU temperature). Speaking of CPU temperature, it's now possible to specify the correct temperature sensor in the config.php file. There is no longer need to manually specify the latitude and longitude values required for fetching weather data for the current location. It's done automatically by obtaining the geographical coordinates from the /run/readsb/receiver.json file. That's all for now. Over and out.
