Fix bare except blocks

[avinxshKD]

There are a lot of bare except: statements throughout the code that catch everything including KeyboardInterrupt and SystemExit. Makes debugging painful, if something hangs you can't even Ctrl+C out of it, and actual errors get silently swallowed

Worst is cwrap.py which has 15+ bare excepts like

try:
    apikey=open(concore.inpath+'1/concore.apikey',newline=None).readline().rstrip()
except:
    apikey = ''

These should at minimum be except Exception: to avoid catching system-level stuff, or better yet catch specific exceptions like FileNotFoundError or IOError depending on what could actually fail. Not critical but would make debugging way easier

Hi @pradeeban ready for review, fixed bare excepts in main repo as asked
And also kept separate from the file I/O refactoring PR. #301

could you also check my previous issues and related PRs to ensure these align with the project's direction? Thanks

Thanks, yes, this is a good one to fix.
