This PR introduces two major improvements to LiteJsonDb

[Yusufibin]

1. Enhanced search functionality: Added support for substring and case-insensitive searches in the search_data method.
2. Configurable logging system: Replaced all print statements with a proper logging system using Python's logging module, allowing users to control log levels and output.

Changes Made

Search Improvements (modules/search.py and LiteJsonDb.py)

• Added optional parameters substring (default: False) and case_sensitive (default: True) to search_data.
• Updated search logic to support partial matches and case-insensitive comparisons while maintaining backward compatibility.
• Improved docstrings to document the new parameters.

Logging System (LiteJsonDb.py and all handler/modules files)

• Introduced a LiteJsonDb logger with console output for user messages.
• Replaced all print statements in handler/db_operations.py, handler/encrypt.py, handler/method.py, modules/search.py, modules/csv.py, and LiteJsonDb.py with appropriate logger calls (logger.error, logger.info).
• Preserved ANSI color codes in log messages for better readability.
• Logging is enabled by default when enable_log=True in JsonDB initialization.

Backward Compatibility

• All existing APIs remain unchanged; new parameters are optional.
• Default behavior matches the previous version (exact, case-sensitive search; console output for messages).

Testing

To test the changes:

1. Import the library: import LiteJsonDb
2. Create a database: db = LiteJsonDb.JsonDB(enable_log=True)
3. Add data: db.set_data('users/1', {'name': 'Alice', 'age': 30})
4. Test search:
   • Exact: db.search_data('Alice')
   • Substring: db.search_data('Ali', substring=True)
   • Case-insensitive: db.search_data('ALICE', case_sensitive=False)
5. Check console logs for messages (e.g., errors on invalid operations).
