How Has This Been Tested?

west build -p -b b_u585i_iot02a ocre-runtime/src/samples/supervisor/zephyr/ -- "-DOCRE_PRELOADED_IMAGES=ocre-sdk/generic/big-sample/build/big-sample.wasm" "-DOCRE_SDK_PRELOADED_IMAGES=webserver.wasm;filesystem.wasm;hello-world.wasm"
west flash --hex-file=build/zephyr/merged.hex
