PCA improvements
Improve the following:
-
Allow PCA also for cases when prenormalized data has been provided -
make colors nicer, use viridis colors -
Scree plots using the same data, remove PCATools dependency, improve legends, one scree plot per nVariablRows value -
automatically convert Dates to proper colors, and logicals -
double-check results look similar to before due to changes
