summarizeWithPca: Summarize Using PCA
In cavei/MOSClip: Multi Omics Survival Clip

Given a matrix it summarize to a 0 or 1

1 2	summarizeWithPca(data, features, name = "pca", shrink = FALSE, method = "regular", cliques = NULL, maxPCs = 3, loadThr = 0.6)

`data`	a data matrix
`features`	a vector with the features to analyze
`name`	prefix of the covariates
`shrink`	shirnk or not the covariance matrix.
`method`	either "regular", "sparse" or "topological"
`cliques`	the features organized in cliques. Only use for topology.
`maxPCs`	maximum number of pcs to consider
`loadThr`	loading threshold
