FFZ badges consume a decent amount of memory in Chatterino. Before this PR, they consumed 18.4 MiB. We can do two cheap optimizations that cut the use in half: - Use [`QVarLengthArray`](https://doc.qt.io/qt-6/qvarlengtharray.html) to store the badges for a user instead of `std::set`. `std::set` always allocates, even if there's only one badge. Since most users only have one, we create many small allocations. With `QVarLengthArray<T, N>`, `N` elements are stored inline. This reduced the memory usage to 11.9 MiB. - Use `boost::unordered_flat_map` instead of `std::unordered_map`. Because of relaxed requirements for the Boost map, it doesn't need to store as much auxiliary data. This reduced the memory usage to 9.3 MiB. A further optimization could be the use of a `boost::container::flat_multimap<std::string, int>`. This gets us to 4.6 MiB. I haven't measured the performance of this. We'd have to assume that FFZ returns us unique users per badge. The comparison with `QString` for the lookup can be done by comparing `QString < QLatin1StringView` (as we know badge IDs are latin1).
