naturaldelta: include OverflowError in the int() guard so float('inf') returns unchanged

The docstring says naturaldelta returns non-number input unchanged. int(float('inf')) raises OverflowError (not ValueError or TypeError), so the existing except (ValueError, TypeError) clause let it escape.

The two new test cases (float('inf') and float('-inf')) fail on the pre-fix code with OverflowError and pass once OverflowError is added to the except tuple. The existing 'NaN' string case still returns "NaN" because str('NaN') is 'NaN' and float('NaN') → nan → int(nan) still raises ValueError which is still caught.
