As IntoIter is only implemented for slices up a sice of 32.
DFAReporting though will reach 55, at least.
Also added dfareporting-cli code to show how stackoverflow issues can be
circumvented efficiently.
We get a stack-overflow when trying to run the dfa-reporting program,
and right now I don't know how to workaround it.
This could be preventing us from using clap.
