06df5038 - chore(analysis/calculus/times_cont_diff): transpose lemmas (#3665)

chore(analysis/calculus/times_cont_diff): transpose lemmas (#3665) In #3639 , I accidentally placed the new lemma `times_cont_diff_at_inverse` between `times_cont_diff_at.prod_map'` and `times_cont_diff.prod_map`. This fixes that.
