Unprocessable Batch bytes

I am trying to get a BNO086 working. I'm getting this error:
```

I'm able to read data every couple of times, but am often getting error messages like this.

Reproduce the intermittent failure with the BNO086 over I2C on a Raspberry Pi Pico using the example shown. Start at adafruit_bno08x/__init__.py lines 379, 803, and 858-863, where the traceback reaches _separate_batch, and compare the received packet bytes with the BNO08x protocol. Done means the reported packet no longer causes an unhandled error and repeated sensor reads are reliable.
