+C++ STL is not welcomed here. Almost every STL header (besides C standard
+library wrappers like `cstring` or `cstdio`) increases compilation times
+significantly. This disassembler is used to be developed on Celeron N4000
+machine with eMMC memory instead of SSD and it is very sensitive to STL bullshit
+increasing compile times. Please, make sure you don't use any compile time heavy
+headers. If you really need something like hashmap or RB-tree, then bring some
+tiny MIT/BSD/Unlicense library from somewhere or write it yourself.
