inplace_vector for C++11 and above
This is an implementation of P0843R14. Note that before C++26 is released, there may be changes to the specification and this implementation will try to stay as close as possible to what actually goes into the final C++26 standard and may therefore change too.
It is feature complete, however a few member functions taking ranges are only available when compiling with C++20 or newer. One constructor is only available with C++23 or newer.
