Any validation we should do on the value? Ie, >0?

As I mentioned in #505, I am proposing the ability to modify the update interval of the statistics file. Despite the compilation error due to issues in the unstable branch, I am submitting this PR to showcase the necessary code changes to declare the update-stats-frequency variable, which is an integer that defines how many seconds will pass before the file is updated. This file will then be read by Prometheus.
Now, it would only be necessary to add the global variable update-stats-frequency = x; in the configuration file (rtl_airband.conf) so that each user can control the frequency at which the statistics are updated. The modified code still maintains the default 15-second interval if this global variable is not specified, just like the original code does.
The reason for proposing this change is that having the option to configure a shorter update interval and allowing Prometheus to read these values more frequently enables more precise statistics, especially for analyzing signal and noise levels, for example.
Thank you, and I apologize for any mistakes that may exist. I'm not very experienced with Git and pull requests.
