Log Profiles​

In addition to the topics logged by the SD card, adding Bit:4 - High rate is enough to get values on actuators, rates, attitude, and sensors. Note that Bit:3 - System identification is a subset of topics included in high_rate topics and so it is not useful to enable them both. Although, enabling both is not harmful. In essence, unless flying on PX4's autonomy, SDLOG_PROFILE:17 is recommended. More details can be found in the PX4 file src/modules/logger/logged_topics.cpp.
