hop_length not working

[cparcerisas]

If I add hop_length parameter to the noise_reduce function, it gives an error:

`
import numpy as np
import noisereduce as nr

This works

nfft = 512
fs = 8000
signal = np.loadtxt('signal.csv')
nr.reduce_noise(y=signal, sr=fs, n_fft=nfft, win_length=nfft)

This does not work

nfft = 512
fs = 8000
signal = np.loadtxt('signal.csv')
nr.reduce_noise(y=signal, sr=fs, n_fft=nfft, win_length=nfft, hop_length=100)
`
I tried with different values and it always gives the same error:

AttributeError: 'SpectralGateNonStationary' object has no attribute '_hop_length'

signal.csv

Same error here.

I found the issue: https://github.com/timsainb/noisereduce/compare/master...fix-hop-length?quick_pull=1

I'll pull this into the python package asap
