Refactor: Replace bare 'except:' with 'except Exception:' to fix E722

[PratapShashwat]

Description
Replaced bare except: clauses with except Exception: in netpyne/specs/netParams.py.

Reasoning
Bare exceptions (except:) catch SystemExit and KeyboardInterrupt, which makes it difficult to stop the program during execution. except Exception: catches all standard program errors but respects system signals (PEP8 E722).

Verification

• Ran flake8 to confirm E722 is resolved.
• Verified via test script that basic functionality remains intact.

@vvbragin Hi Valery, thank you for reviewing and merging this!

I am very interested in continuing to contribute to NetPyNE for GSoC 2026. I noticed the INCF ideas list is currently undergoing revisions and NetPyNE isn't listed at the moment. Are there plans for NetPyNE to participate this year?

I have a background in running ML models on supercomputing clusters and managing SLURM workflows, and I saw a previous NetPyNE project focused on ML/AI Parameter Tuning and the batch subpackage. I would love to tackle an issue in that domain or even submit a proposal for it if INCF is accepting independent ideas.

Let me know if there's a better place to discuss this!
