Negative values between -1 and 0 should have a "minus" before the textual number
Actual Behaviour
Missing "minus"
It does work correctly for values lower than -1
Steps to reproduce
import num2words
num2words.num2words(-0.01)
# 'zero point zero one'
# below -1 it's correct again
num2words.num2words(-1.01)
# 'minus one point zero one'
Expected Behaviour
Negative values between -1 and 0 should have a "minus" before the textual number
Actual Behaviour
Missing "minus"
It does work correctly for values lower than -1
