Nicla Vision MicroPython Deep Sleep Example

# Deep Sleep Mode Example
# This example demonstrates the low-power deep sleep mode plus sensor shutdown.
# Note the camera will reset after wake-up from deep sleep. To find out if the cause of reset
# is deep sleep, call the machine.reset_cause() function and test for machine.DEEPSLEEP_RESET
