This avoids issues with doubling the measurement vector sizes influencing memory measures.

Remove easy profiler for now. It might be useful for later on to get a grasp of general behaviour, but because of its issues with coroutines it is not worth profiling code with it right now.

It is now possible to use a memory mapped stack that throws a SIGSEV if thes coroutine stacks are exhausted.

The idea is to exclude as many sources as possible that could lead to issues with contention and cache misses. After some experimentation, we think that hyperthreading is simply not working very well with our kind of workload. In the future we might simply test on other hardware.

Now all algorithms are used without the parallel pre-/suffix and the for_each method has an specialization for integer ranges.
