feat(idsueye): Add exposure range validation and query support

Browse Source 
- Query camera's actual exposure range before setting exposure time
- Validate and clamp exposure values to supported min/max limits
- Log detailed information about range, requested vs actual values
- Add GET_EXPOSURE_RANGE command to UDP control interface
- Update Python control scripts with exposure range query support

This prevents IS_INVALID_EXPOSURE_TIME errors and ensures values are
always within the camera's capabilities. The exposure range varies by
framerate and sensor configuration.
