What is the issue that you would like suricata-check to detect and report on?
Similar to the already implemented issue in https://github.com/Koen1999/suricata-check/blob/master/suricata_check/checkers/community/unexpected.py, the same issue exists for flowbits, which should also be checked.

What is the impact of the issue?
The usage of flowbits: set in together with threshold may result in unexpected behavior and therefore lead to False Positives.

Additional context
Suricata has documented the effects of this combination here.
