[Feature] Ability to set labels for Touch Bar items other than Fn keys
tl;dr it2setkeylabel.sh for keys other than Fn.
As previously alluded to in #5281 (closed), it'd be good if the functionality present to assign custom labels to Fn keys was extended to single Touch Bar items. Basically I'd like to add an item, assign it a 'noop' (i.e 'Ignore'), give it a label, and then address it via that label and update it with some output from my shell.
This for me is preferable to adding all the Fn keys to my Touch Bar, most of which I don't use.
Thanks!
