The current solution is to sequentially test one mutation after another. This is extremely inefficient since most of the time is spend in the execution command. A parallel solution is needed.

• Make it possible to define a "worker amount" via the binary
• Make the generation of the mutations concurrent (no need to add workers here since the mutation generation is not the bottleneck)
• Create a version of simple.sh which runs tests in a temporary folder -> isolate the test execution
