inconsistent description in kmeans_inference_1f

[szcf-weiya]

The description in kmeans_inference_1f seems not consistent on the page https://yiqunchen.github.io/CADET/reference/kmeans_inference_1f.html

At first, it says the default is independent features.

But in the later explanation of parameters, the default is dependent features (but without default covMat

BTW, I caught a typo

And I have a related question. It seems that one should always estimate (or "know") covMat before using the function? Would it be practical when the number of features is too large, e.g., single cell dataset? And do you think how to take the estimation of covMat into account in the whole clustering-testing procedure instead of assuming covMat is given? Thanks.
