Enhance IR control functionality and configuration

- Updated angle_minus value in config.json for switch calibration.
- Added support for seminsu devices in load_seminsus function.
- Implemented polling logic for seminsu devices in main.py.
- Adjusted switch position representation from "-" and "+" to "1" and "0".
- Introduced IRRxTxPollPair class for IR communication in ir_pair.py.
- Created ir_test.py for testing IR functionality with configurable parameters.
