Fix bare except in _read_load_local_packet: use except Exception

[koteshyelamati]

In _read_load_local_packet, the bare except: clause catches BaseException, which includes KeyboardInterrupt and SystemExit. This can suppress Ctrl+C interrupts and interpreter shutdown signals.

# Before
try:
    sender.send_data()
except:
    self.connection._read_packet()  # skip ok packet
    raise

# After
try:
    sender.send_data()
except Exception:
    self.connection._read_packet()  # skip ok packet
    raise

Since send_data() raises normal Exception subclasses (like OSError, IOError) and the clause re-raises anyway, except Exception: is the correct scope here. KeyboardInterrupt and SystemExit should propagate without the cleanup step.
