新增构建ISO的工作流

.github/workflows/build-iso.yml

+# 此工作流是为了构建一个immortalwrt固件的安装器 格式为iso 可用于所有的虚拟机 和 物理机
+# 所谓安装器就是用来安装用的 iso引导的是一个启动速度极快的debian live系统 跑码后输入命令 ddd 即可调出安装菜单
+# 安装时 若是多张硬盘 你可以选择 需要安装的硬盘 此类方法安装的openwrt 安装后是有剩余空间的 更多信息请参考 wukongdaily/img-installer 项目
+# 几乎所有linux 都有各自的安装器 唯独openwrt和armbian 没有, 希望此工作流 弥补这个遗憾 让你更优雅的 安装openwrt
