cll.cpp fails to compile

[yukarpenko]

hi Nils! [testing the way of communicating fixes via "Issues" on Github] -- it seems that with GCC 12.2 and possibly GCC 14, the recent addition you've made prevent cll.cpp from being successfully compiled. With GCC 11, it still looks ok.
I've realised it might be an issue indeed, as std::vector is used in type declarations in cll.h, but #include is not there yet.
So as a temporary fix, I tried adding #include in cll.h, and it fixes the compilation issue -- would this fix look consistent to you?

Hi Iurii, indeed I did not realize that I have missed the #include <vector> in cll.h. I am wondering why I did not run into this issue, even with the missing include directive, but you are right, to fix this issue, one needs to add #include <vector> in cll.h. Do you want me to open a PR for it?

hi Nils - please don't open the PR just yet. I'll ask a colleague of mine who uses GCC 14 and apparently has issues not only with cll.h btut other files. My understanding is that including and other "standard" headers in header files is ok, so it should be an easy fix.
