Release v1.6.0

Version 1.6.0 enhances the bluetooth-terminal library with a modernized configuration system, improved logging capabilities, and better connection management while maintaining backward compatibility through deprecated method support.

API Enhancements

• Added new onReceive callback for message handling.
• Renamed methods for better consistency (e.g., setOnConnected → onConnect) while keeping old methods as deprecated.
• Added setCharacteristicValueSize to configure maximum data chunk size.
• Improved parameter naming for clarity (data → message).

Configuration System

• Introduced options object for more flexible configuration while maintaining parameter-based initialization.
• Refactored the constructor to accept both the options object and legacy parameters.
• Enhanced error handling with more specific error messages.

Logging System

• Implemented comprehensive logging with multiple levels (none, error, warn, info, log, debug).
• Added onLog callback for custom logging integration.
• Created context-aware logging with method names and descriptive messages.

Connection Management

• Refactored connection logic for better reliability.
• Improved reconnection mechanics.
• Enhanced error handling during connection and communication.

Documentation & Testing

• Updated README with revised introduction, quick start guide, and API documentation.
• Improved JSDoc comments throughout the codebase.
• Reorganized tests into separate files for better maintainability.
• Expanded test coverage for new features.

Other Improvements

• Maintained backward compatibility with no breaking changes.
• Updated dependencies to the latest versions.
• Improved consistency with Arduino BluetoothTerminal library.
• Removed splitByLength method due to implementation simplification.

This release focuses on developer experience improvements while ensuring existing implementations continue to work without modification.
