承接昨天写的《JPEG软解码实现介绍》，今天介绍其使用方法和一些细节说明。
1.仓库下已经包含了几个jpeg文件，以方便直接校验。
2.使用命令分为两种模式。
一种是直接解码为yuv文件，另外一种是解码的同时还dump所指定mcu位置的各阶段值。
内部默认设置为输入文件名后再跟stride_w/h和yuv格式信息，如输入文件为animal_park.jpg，输出文件内部自动设置为animal_park_992_720_yuv420.yuv。
另外补充一点，输出文件名的992_720并不一定是真的宽高，是经过对齐后的值（stride）。
提供给播放器crop信息，可以根据实际的宽高进行部分显示，否则图像的底部和右侧会出现多余的图像。
文件名后补充该值的目的是为了方便yuvplayer工具显示，因为必须要指定宽和高的信息。
4.向什么值对齐要视采样因子而定。
A.如果是yuv444（y分量水平和垂直采样因子都是1），那么宽高都是8对齐；
B.如果是yuv420的（y分量水平和垂直采样因子都为2），那么宽和高都是16对齐；
C.如果是矩形的mcu采样，像8x16(y的h_factor/v_factor分别为1和2)的，宽向8对齐，高向16对齐，另外一种是16x8的，分别向16和8对齐。
5.使用示范。
模式1下，实例命令为：./JpegDecoder animal_park.jpg
其结果信息显示为：
$ ./JpegDecoder animal_park.jpg
