建议增加 类型检测/循环次数/UnclampedDelayTime/DelayTime 的支持

1.目前SVGA是ProtoBuf二进制格式+zlib压缩, 单独zlib格式无法检测是否是svga格式,建议在最终的二进制前面的特定位置加上特定的tag,用于检测是否是SVGA格式,基本信息(如FPS,时长,是否包含音频,音频格式)等.
2.建议支持 LoopCount/UnclampedDelayTime/DelayTime 等特性, 对标GIF 和 Animated WEBP等标准动图格式.
3.长远看,建议按照标准图片二进制格式定义SVGA的二进制文件, 将会是为数不多的支持播放声音的动图格式

SVGA 3.0 的格式会尽量参照标准的视频、图片格式设计。
