First spike for BNO085 integration

[Johannes-Thiel]

We want to integrate the BNO085 into Lizard. This spike is an implementation of the Adafruit_BNO08x
component. I also created an I2C master module to prevent code duplication.

I wonder if Adafruit_BNO08x should be included as a Git submodule instead of copying the plain source code... 🤔

[Johannes-Thiel]

Yes it should be includet as a git submodule. I think I did someting wrong in the configuration. I will look into it.

[Johannes-Thiel]

The submodule is not a proper idf component. In order to use it as a git submodule we will need to fork the driver and add a CMakeLists.txt with

idf_component_register(
    SRCS
        "Adafruit_BNO08x.cpp"
        "sh2.c"
        "sh2_util.c"
        "sh2_SensorValue.c"
        "shtp.c"
    INCLUDE_DIRS "."
    REQUIRES driver esp_timer freertos
)

With that fork. we would be able to include it as a submodule.
