Correctly implement mean denoiser

Browse Source 
Used to have:

```py
imageDenoisedNpArray = imageNpArray - means[color]
imageNoiseNpArray = imageNpArray - imageDenoisedNpArray
```

so:

```py
imageNoiseNpArray = means[color]
```

then we mean the mean...

While should have:

```py
imageDenoisedNpArray = means[color]
```
