This PR adds four lemmas that calculate the norm of the (n+1)st iterated derivative as the left and right composition
iterated_fderiv
andfderiv
with version for bothiterated_fderiv
anditerated_fderiv_within
.While these lemmas are borderline trivial, they are very useful and finding
linear_isometry_equiv.norm_map
might be unintuitive.
