scTransform support

Hi @bli25 et al.,

Thank you for developing this incredible toolkit! Is has saved our team so much time and effort in our single-cell analysis workflow. We are very interested in using an scTransform-like approach to normalize the raw counts in-place of log_norm. Have you considered adding a scTransform function for normalization?

It looks like there are some python implementations out there:
