Minio存储相关功能优化建议

近期使用Bladex对接minio存储，发现通过Bladex上传的图片、文件等的contentType都是默认的application/octet-stream格式，无法直接预览，查看源码发现，在MinioTemplate中将contentType固定写成了application/octet-stream，建议修改支持自动识别文件格式！

示例代码如下：

public class MinioTemplate implements OssTemplate {
 
 
    /**
     * .........
     */
 
    @Override
    @SneakyThrows
    public BladeFile putFile(String bucketName, String fileName, InputStream stream) {
        return putFile(bucketName, fileName, stream, ViewContentType.getContentType(fileName));
    }
}
 
 
public enum ViewContentType {
