'U' flag has been deprecated since Python 3.3

Hi,

I get this error message when trying to execute parsac in the Python 3.11.5:

ValueError: invalid mode: 'rU'

From what I can read on the web, it seems U file mode was removed in Python 3.11 because it had no effect so the U can merely be removed.

If I change 'rU' in program.py and gotm.py, I do not get the error message and I can execute parsac calibration.

Cheers,
