jsflowers 2025 attempt 1 (save load)

	1. 需要字体: Ume P Gothic, IPAmjMincho
	2. 文件结构
	game_ete/
	bgimage/
	bgm/ (所有BGM文件名改为全小写)
	... 除script.iga外其他iga文件解压，每个一个文件夹
	scripts.js 使用我的 flowerscript-js 反编译的脚本，组合成一个js: const game_script = { "脚本文件名.s": { 反编译结果 }, ... };
	index_hiver.html
	index.js (ts编译后)
	3. 运行方法

	.Struct => \|st\| st,
	else => @compileError("T must be a struct"),
	};
	var newFields = info.fields[0..info.fields.len].*;
