Initial commit: Complete USB2CAN cross-platform framework

Features:
- Cross-platform support (Windows/Linux/macOS)
- CAN and CANFD protocol support
- USB communication (WinUSB/libusb)
- Device management and configuration
- Message transmission and reception
- Filter configuration
- CMake build system
- Comprehensive examples and tests
