Update utils.py

[Art200696]

While working with CVAT, annotations are being saved as float. Hence python cant interpret them directly as int.

Do you get an error with the existing code, as in int(box[0].text) doesn't work? If so, could you share the code as well as provide an example XML file that causes the error? Just so I can get a better feel for what's going on.

'
from detecto.utils import xml_to_csv
import pandas as pd

df = xml_to_csv('../Annotations/')
`

error -

ValueError: invalid literal for int() with base 10: '757.361328125'
