2022xxxx Version 2.0.x full customizer user interface,case configuration file changed to json,
accessories kept in sbc_case_builder_accessories.cfg,
added round, hexagon, snap and fitted cases, setup additional sbc from SBC_Model_Framework,
added components and masks, added associated parametric positioning for accessories
added components and masks, added associated parametric positioning for accessories,
added individual variable height standoffs
