Function allows users to update label of any explainer in a unified way. It doesn't require knowledge about structre of an explainer.
update_label(explainer, label, verbose = TRUE)- explainer object that is supposed to be updated.
- new label, is going to be passed to an explainer
- logical, indicates if information about update should be printed
updated explainer object
