Detailed Description

Logs messages to files with date-based rotation and automatic deletion of old logs.

This logger writes logs to files organized by date. It supports asynchronous logging and manages old files based on a configurable retention period.

Key Features:

Date-based file rotation.
Automatic cleanup of old files.
Synchronous or asynchronous operation.
