[C++] 15 FLTK：Fl_Radio_Round_Button

[M1 Mac, Big Sur 11.6.5, FLTK 1.3.8]

PyQt6アプリのGUI画面を移植しました。

Fl_Round_Buttonはラジオボタン機能を持っていないただの丸いボタンだったので、Fl_Radio_Round_Buttonに変更しました。

ガワだけというのもありますが、爆速な起動に改めて感動しました。こうじゃないとC++を扱う意味がありません。

FLTKのあまりの癖の強さにGTKへの移行を考えたのですが、メンバ関数名の余計な変更など向こうの方がやりたい放題でした。やっぱりこちらのお世話になります。
