  1. fix: workaround servertech_sentry3 zero-length integers 

    servertech_sentry3 devices can return bad ASN.1 data, an Integer with
asnlength=0 under certain cases.

- Certain firmware versions only
- SNMP BULKGET
- Specific OIDs deep into the tree, at different repetition values

Work around the problem by setting max_repetitions=4, which doesn't
trigger the device bug.
