Add --enable-tcy flag to detect and correctly OCR horizontal text embedded in vertical lines (tate-chuu-yoko), commonly found in newspaper headlines (e.g. "4317" in "全国4317人不足"). - TateChuYokoWrapper segments vertical line images into blocks and identifies TCY regions by horizontal component analysis - Filter noise blocks (height < seg_min_gap) from TCY detection - Use max_aspect_ratio=0.75 to avoid false positives on regular kanji - All TCY parameters are tunable via --tcy-* flags

縦書きテキスト中に含まれる横書き部分(縦中横)を検出・認識する機能を追加しました。新聞などで数字や英字が横書きで組まれているケースに対応します。
--enable-tcyフラグで有効化するオプトインになっているので既存の動作には影響しません。また指定しない時はロードすらされません。指定すると以下
tcy_wrapper.pyをロードし PARSEQ をラップします。--enable-tcy指定時のみ--tcy-*パラメータで検出の閾値等を調整できます。この機能を使う場合には cv2 が必要になります。
