No module named 'confluent_kafka.cimpl'

How to reproduce:
Deploy AWS Lambda function with Python 3.9 runtime and try to import:

from confluent_kafka import Producer

When confluent_kafka version 1.8.2 is used it returns an error:
No module named 'confluent_kafka.cimpl'

Works with Python 3.7 and confluent_kafka version 1.7.0.
