Initial commit: ESP32-S3 UWB positioning system

- Added anchor and tag implementations for MaUWB modules
- Configured for 6.8Mbps communication with range filtering
- Support for multiple tags (tag/tag2 environments)
- OLED display integration for real-time measurements
- Simplified code without sleep mode and OTA functionality
- Complete UWBHelper library for AT command interface
