抛弃mode参数,现在由程序自动选择mode1或者mode2,用户不用关心

There is no need for param:'mode' now; Automatically determine mode 1 or mode 2;

auto mode:

 mode0(default): Universal structure (look like exceldata.dat)
 mode1: Universal structure (look like syokibugu)

解决 idata.dat 不能解包的问题

Resolve the issue of idata.dat not being able to unpack
