Replaces conditional in nlShrinkLWEst to use (p <= eig_nonzero_tol) instead of (p <= n), resolving the primary point of https://github.com/PhilBoileau/cvCovEst/issues/23, which is only an issue at certain sample size and dimensionality settings.
Also makes minor touch-ups throughout, including documentation re-styling, code re-styling via styler, minor README fixes, and improvements to auxiliary files (.Rbuildignore, .gitignore).
