Is your feature request related to a problem? Please describe.

Often when performing operations on images our solution will greyscale an image on importing it. In my own project I have a set of images I want to run several image metrics on. So i have already turned the images from multi-channel to single-channel. However now when I call score(image) I get an error saying the image cannot be grayscaled.

Describe the solution you'd like

The 'Score' method should check the channels of an image and grayscale it only if the channels > 1. else it should proceed without attempting to grayscale the already single channel image.

Describe alternatives you've considered

Adding fake channels to my grayscale so it appears to be multichannel

Hi, wonderful job.
I was wondering if adding an input of Ndarray image would be more useful in practice. I personally use brisque to read images from videos, so that in this way using Ndarray image as input seems more friendly to users.
No worries, I already change the source code to achieve reading Ndarray, but I think for further improvement, maybe my suggestion could be helpful.

Hello, Thank you for providing this amazing repository.

I was wondering if there are min and max values for brisque score.

Thanks in advance.
