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

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