* rework I2C sensor init the goal is to only instantiate sensors that are pressend to save memory. side effacts: - easyer sensor integration (less C&P code) - nodeTelemetrySensorsMap can be removed when all devices are migrated * add missing ifdef * refactor a bunch of more sensors RAM -816 Flash -916 * fix build for t1000 * refactor more sensors RAM -192 Flash -60 * improve error handling Flash -112 * fix build * fix build * fix IndicatorSensor * fix tracker-t1000-e build not sure what magic is used but it works * Apply suggestion from @Copilot Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Apply suggestion from @Copilot Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Apply suggestion from @Copilot Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update src/modules/Telemetry/Sensor/DFRobotGravitySensor.h Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Fix --------- Co-authored-by: Ben Meadors <benmmeadors@gmail.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>
