This function will re-code _gene_ cluster labels based off of a mapping provided by the user, for all fields on a celda object involving cluster labels. e.g. if Y (gene cluster) values range from 1-4 and the user would like all 3's switched to 1's and vice versa, this function can be useful. NOTE: it is recommended that this function's results aren't used to overwrite the original celda model object provided, in the event of a mis-mapping.
