### Initialize CharlieWing Display and Control Pixels

Source: https://adafruit-circuitpython-is31fl3731.readthedocs.io

Initializes the CharlieWing display using I2C, fills all pixels, and demonstrates controlling individual pixels by turning them off, setting low brightness, and then higher brightness.

```python
from adafruit_is31fl3731.charlie_wing import CharlieWing
import board
import busio
with busio.I2C(board.SCL, board.SDA) as i2c:
    display = CharlieWing(i2c)
    display.fill(127)

    # Turn off pixel 4,4, change its brightness and turn it back on
    display.pixel(4, 4, 0)   # Turn off.
    display.pixel(4, 4, 50)  # Low brightness (50)
    display.pixel(4, 4, 192) # Higher brightness (192)

```
