feat: Add Fichero D11s thermal label printer support with REST API and CLI

- Implemented a new module for the Fichero D11s thermal label printer, including BLE and Classic Bluetooth interfaces.
- Created a REST API using FastAPI to manage printer status, info, and printing tasks (text and images).
- Developed a CLI for direct printer interaction, allowing users to print text and images, check status, and modify settings.
- Added image processing capabilities for converting text and images to the required format for printing.
- Introduced error handling for printer operations and connection management.
- Included a shell script for running the API server with configurable parameters.
- Added English translations for configuration options.
- Created a repository metadata file for project management.
