 We will now smooth the Pearson residual by PCA. Internally `smooth_via_pca` performs PCA, then keeps only significant dimensions and back-rotates to the original data space. The number of significant dimensions is determined using the 'elbow' method. To speed things up we could also use only a subset of the genes for this operation (e.g. variable genes).
