Integrate calibration loading and add comprehensive mode support
- Automatically load calibration constants in begin() method - Remove separate getCalibrations() call from example sketch - Add selectable measurement modes in example with commented options - Implement proper SOC (Start of Conversion) triggering for step modes - Support all measurement modes: Continuous, Step, and Sleeping Step - Optimize loop for efficient new data flag handling - Add automatic single measurement triggering for step-based modes - Tested and verified both continuous and step mode operation - Apply clang-format code formatting to all C++ files 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
