fix: Ignore unsupported command responses (cmd:Unknown, code:1)

Previously, responses with code:1 and cmd:Unknown would be processed
and could cause issues. Now these responses are properly ignored with
a debug log, matching the Python implementation behavior.

This prevents error spam when polling for state on cameras that don't
support certain features.

Closes #1
