Description

Re this thread:
https://forums.adafruit.com/viewtopic.php?t=204722

Poster is using Airlift version.

Seeing same thing on non-Airlift (PID 5600) version:
```python
Adafruit CircuitPython 8.2.6 on 2023-09-12; Metro MIMXRT1011 with IMXRT1011DAE5A
>>> import board
>>> import adafruit_mlx90640
>>> i2c = board.STEMMA_I2C()
>>> mlx = adafruit_mlx90640.MLX90640(i2c)
Traceback (most recent call last):
File "", line 1, in
File "adafruit_mlx90640.py", line 95, in __init__
File "adafruit_mlx90640.py", line 839, in _I2CReadWords
OSError: [Errno 5] Input/output error
>>>

Research direction

Start by reproducing the reported initialization on the Metro MIMXRT1011 with CircuitPython 8.2.6, then inspect adafruit_mlx90640.py at lines 95 and 839, where the traceback enters and fails. Compare the reported Airlift and non-Airlift hardware cases; done means the initialization no longer raises the reported I/O error or the hardware limitation is clearly documented.
