ハートに16連射。（９）

スプライト描画モジュールの暫定版を作ってたり。
復刻版の挙動を参考にしてるのでスーパーやプロとは若しかしたら違うかも。
時計、ストップウォッチ、連打計測、サイコロゲーム、スロットゲーム、
それから「いい加減時計」の”コロ”表示まで考えるとセグをビットで扱うのが無難かなと。
あとゼロサプレスの有無だったり、任意のセグを非表示とか、そういった部分を
int 型（10進6桁）1つで扱うのは無理なので。

んで、折角だから下記の内蔵時計サンプルを関数化して
内蔵時計表示までさせましたよと。

スプライト初期化処理、アップデート処理と、
printf 部分をまんまスプライトに定義を挿げ替えればこのモジュールは出来上がり。のハズ。
