Implement logging level support in Channel and its derived classes

- Added LogLevel parameter to Channel constructor and updated derived classes (FileChannel, StdoutChannel) to accept it.
- Modified log methods to respect the logging level, preventing lower priority logs from being processed.
- Updated Log class to set logging levels for stdout and file channels.
- Adjusted main function to initialize logging with specified levels.
