版本情况

JDK版本： jdk8
hutool版本： 5.3.10

问题描述（包括截图）

image

经过测试，不同的wav文件，文件流头部16进制字符串格式为

52494646xxxxxxxx57415645666D74201200000006000100401F0000

中间的8个x都不同，下面FileTypeUtil类中fileTypeMap这么写，应该是不对的

fileTypeMap.put("52494646e27807005741", "wav"); // Wave (wav)
  1. 测试涉及到的文件，下面的测试文件下载有效期：2022:12:18 16:11:53
