Logging to custom stream or file

[d4h0]

Hi,

Would it be possible to add the ability to log to a custom stream or file?

This would be useful for CLI applications where the user interacts with the application (e.g., application that uses dialogs, REPLs, and TUI application).

Right now, it seems, roarr wouldn't be usable for such applications.

This also would enable to display the logs in a separate terminal window (e.g., tail $log_file | roarr), which itself would be a useful feature (e.g., if you are only interested in the logs when something bad happens).

With this approach, it also would be possible to change the configuration of roarr CLI (e.g., changing its filter configuration) while the main application is still running.
