Fix for Empty except

[Andrey1994]

To fix this without changing functionality, keep ignoring socket.timeout but add an explanatory comment in that except block clarifying that timeout is expected in the receive loop and should not interrupt streaming/sending logic.

Best single change:

• File: emulator/brainflow_emulator/biolistener_emulator.py
• Region: run() method, try/except around recv, specifically the except socket.timeout: block (around lines 168–169).
• Replace the empty pass with a commented no-op:
  • Add a short comment (e.g., “Expected when no command arrives within socket timeout; continue loop.”)
  • Keep pass to preserve behavior.

No imports, new methods, or dependency changes are needed.
