chk_log_value spams the debug log with suppressed errors

[daniel-montanari]

Not super important, I just noticed when looking through the atdev log for testing NATA scripts there were a hundred lines of silent errors with the formatter. My understanding is that logging values should be fairly arbitrary in the data that is accepted, and I don't see the value in rounding logged things.

Maybe when we get onto 3.13 we can figure out how to use generics to make it clearer what values a check and all its methods expect.

def chk_log_value(test_val, description="", fmt=None) -> bool:
    """Log test_val"""
    return _message_parse(
        test_val=test_val,
        target=_log_value,
        description=description,
        formatter=_format_testvalue,
        fmt=fmt,
    )
...

def _format_testvalue(chk: _CheckClass) -> str:
    fmt = chk.fmt if chk.fmt is not None else ".3g"  # Default
    return f"{chk.status}: {chk.test_val:{fmt}} : {chk.description}"

ValueError: Unknown format code 'g' for object of type 'str'
