方法名：skip

IOUtils.skip介绍

[英]Skips the given number of bytes by repeatedly invoking skip on the given input stream if necessary.

In a case where the stream's skip() method returns 0 before the requested number of bytes has been skip this implementation will fall back to using the read() method.

This method will only skip less than the requested number of bytes if the end of the input stream has been reached.
[中]如果需要，通过在给定的输入流上重复调用skip来跳过给定的字节数。
如果流的skip（）方法在请求的字节数被跳过之前返回0，则此实现将退回到使用read（）方法。
如果到达输入流的末尾，此方法将只跳过小于请求字节数的字节。
