feat(app): stroke order for kanji and kana, from KanjiVG KanjiVG's strokes come with the app (assets/kanjivg/, CC BY-SA 3.0, its notice in the licence list): 94 gzipped files, one per 256 code points, 2.7 MB in all, a file read the first time a character of it is asked for (StrokeRepository, app-wide beside the maps). The strokes are SVG path data, read with path_parsing (the Flutter team's, pure Dart, already in the build through flutter_svg), so the model can flatten them into points without dart:ui, as checking handwriting will. A character's sheet traces its strokes in order over those to come, with its stroke count, meanings, readings, level and the components KanjiVG splits it into, each a tap away. It opens from a studied character's answer (Stroke order) and from a character found in the dictionary.
