pipeline: raspberrypi: Read config parameters from a file
Add the ability to read the platform configuration parameters from a config file provided by the user through the LIBCAMERA_RPI_CONFIG_FILE environment variable. Use the PipelineHandler::configurationFile() helper to determine the full path of the file. Provide an example configuration file named example.yaml. Currently two parameters are available through the json file: "min_unicam_buffers" The minimum number of internal Unicam buffers to allocate. "min_total_unicam_buffers" The minimum number of internal + external Unicam buffers that must be allocated.
