Refactor Marlin2 component and add new features

- Updated __init__.py to include max_sd_files configuration option.
- Refactored Marlin2 class to use new namespaces and improved structure.
- Added support for binary sensors and select components in binary_sensor.py and select.py.
- Enhanced sensor.py and text_sensor.py to include new configuration options for SD card file count and selected file.
- Improved code readability and organization across multiple files.
