Non-integer confidences cause error parsing

[whikloj]

If your confidence is not a whole number then parsing it throws an Exception at line 186 of parse.py

ValueError: invalid literal for int() with base 10: '0.988'

Code that offends is.

conf = int(m.group(1).split()[0])

You can also just test this with any old python.

> python3 
Python 3.11.6 (main, Oct  2 2023, 13:45:54) [Clang 15.0.0 (clang-1500.0.40.1)] on darwin

>>> print(int("99"))
99
>>> print(int("99.9"))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '99.9'

Solution is to convert to float() first.

conf = int(float(m.group(1).split()[0]))

>>> print(int(float("99.9")))
99
>>> print(int(float("99")))
99

or perhaps use the float instead of an integer
