Uses C++ with exceptions enabled, esp_lcd as display driver with LVGL for UI rendering
esp-idf-cxx in IDF registry is currently bugged and can't be built, if e.g. their I2C component is used, until a release with this PR, so for now I moved it to components, patched and added to .gitignore.
There's also a component for SCD30 sensor, I plan to implement HALs for all sensor used here at some point, but I'm not sure yet if I really need this.
