* First addition of __has_include for sensor support * Add __has_include blocks for sensors * Put BMP and BME back in the right sensors * Make TelemetrySensor::setup() a pure virtual finction * Split environmental_base to environmental_extra, to compile the working sensor libs for Native * Remove hard-coded checks for ARCH_PORTDUINO * Un-clobber bmx160 * Move BusIO to environmental_extra due to Armv7 compile error * Move to forked BusIO for the moment * Enable HAS_SENSOR for Portduino * Move back to Adafruit BusIO after patch
