simple_stack_vector bad range check

[n-co]

range check at at functions should probably be if (idx >= size_) instead of if (idx > size_)

  [[nodiscard]] constexpr value_type &at(const std::size_t idx)
  {
    if (idx > size_) { throw std::out_of_range("index past end of stack_vector"); }
    return data_[idx];
  }


  [[nodiscard]] constexpr const value_type &at(const std::size_t idx) const
  {
    if (idx > size_) { throw std::out_of_range("index past end of stack_vector"); }
    return data_[idx];
  }

Merged, thank you.
