            The partition table to flash to the ESP32. The partition table
            determines where apps, data and other resources are expected to
            be found.

            The predefined partition table CSV descriptions can be found
            in the components/partition_table directory. These are mostly intended
            for example and development use, it's expect that for production use you
            will copy one of these CSV files and create a custom partition CSV for
            your application.

                This is the default partition table, designed to fit into a 2MB or
                larger flash with a single 1MB app partition.

                The corresponding CSV file in the IDF directory is
                components/partition_table/partitions_singleapp.csv

                This partition table is not suitable for an app that needs OTA
                (over the air update) capability.

            help
                This is a variation of the default partition table, that expands
                the 1MB app partition size to 1.5MB to fit more code.

                This is a basic OTA-enabled partition table with a factory app
                partition plus two OTA app partitions. All are 1MB, so this
                partition table requires 4MB or larger flash size.

            The address of partition table (by default 0x8000).
            Allows you to move the partition table, it gives more space for the bootloader.
            Note that the bootloader and app will both need to be compiled with the same PARTITION_TABLE_OFFSET value.

            This number should be a multiple of 0x1000.

            Note that partition offsets in the partition table CSV file may need to be changed if this value is set to
            a higher value. To have each partition offset adapt to the configured partition table offset, leave all
            partition offsets blank in the CSV file.
