pcaMuffle: Muffle the pca function
Description
PCA and Q2 issues warnings about biasedness and poorly
estimated PCs. The first is non-informative and the
poorly estimated PCs will show up as poor overfitting
which leads to a choice of fewer PCs i.e. not a problem.
This function is mean to muffle those warnings. Only used
for version of pcaMethods before 1.26.0.
