SLIDE CV + feature_names_list + do_interacts

[TranscriptionFactory]

-updated optimizeSLIDE to save SLIDE_LFs after running getTopFeatures; also saving the yaml file for each specific run (so that if someone wants to run SLIDEcv they can either use the yaml from a single run or use the original yaml thats used to run -optimizeSLIDE to run CV for all the runs) -updated SLIDEcv function to work after running optimizeSLIDE -changed SLIDEcv output plots to be ggpubr (the nice ones with the stats) -changed "gene_list_Zxxx" to be "feature_list_Zxxx" -added args in CV functions so that if do_interacts is False then CV is done without interacts

tested & looks good but having issues building vignette because of path issues. maybe make a loaded yaml file an input to the SLIDE cv function?
