URL: https://github.com/apache/nuttx-apps/pull/4031
## Summary
Add an example of the nPZero G1S driver for the sensors of the nPZero G1S
Development Kit, like the example of the Nanopower driver API:
* LIS2DW12 accelerometer on peripheral 3 (SPI), read every 5 s, wakes the
host up above about 61 mg on X.
* AS6212 temperature sensor on peripheral 4 (I2C), read every 30 s, wakes
the host up above 25 C or below 10 C.
* Global time-out of 300 s.
At each boot of the host it shows the ID and the wake-up reason (with the
values of the peripherals and of the ADC that triggered it), sends the
configuration and, after CONFIG_EXAMPLES_NPZERO_IDLE_DELAY ms, enters Idle
state, which switches the host off. "npzero -s" shows the status only. Both
sensors are kept powered while the host is on (pswint): an unpowered AS6212
board blocks the shared I2C bus.
## Impact
Users will be able to use this app as reference to implement their own low
power sensor configuration
## Testing
Tested on the DevKit with npzero-g1s-dk:nsh:
```
nsh> npzero -s
nPZero G1S ID: 0x60
STA1: 0x01 STA2: 0x00
nsh> npzero
nPZero G1S ID: 0x60
STA1: 0x01 STA2: 0x00
Configured, Idle state in 1000 ms
```
