Provide nice Unicode symbols for fractional exponents wherever possible.

using namespace units;
using namespace units::si::literals;

std::cout << sqrt(1m) << "\n";

It would be nice if we could somehow pass a required Vulkan version (both instance and physical device) as well as required extensions (instance and device) to app.
The best place would probably be in frame_config since both frame and app have access to it.

Stefan Kurtz reported the following issue over our seqan-dev list:

1. I followed the description for the Cmake-setup and noticed in the example CMakeList.txt shown at the end of https://docs.seqan.de/seqan/3-master-user/setup.html that compiler optimization options such as -O3 is missing, which will lead to poor performance for users who do not recognize it.
