Enhance configureInterrupt with interrupt source selection

Browse source 
- Add bmp5xx_interrupt_source_t enum for interrupt source types
- Update configureInterrupt() to accept interrupt sources parameter
- Support combining multiple interrupt sources with bitwise OR
- Add data ready, FIFO full, FIFO threshold, and pressure out-of-range sources
- Maintain backward compatibility with default data ready source
- Update I2C example to demonstrate new interrupt source parameter
