golang+libreffice6.2实现word,excel,pptx转pdf,html

方法[^本地需安装libreoffice]

/**
*@tips libreoffice 转换指令：
* libreoffice6.2 invisible --convert-to pdf csDoc.doc --outdir /home/[转出目录]
*
* @function 实现文档类型转换为pdf或html
* @param command:libreofficed的命令(具体以版本为准)；win：soffice； linux：libreoffice6.2
*     fileSrcPath:转换文件的路径
*         fileOutDir:转换后文件存储目录
*       converterType：转换的类型pdf/html
* @return fileOutPath 转换成功生成的文件的路径 error 转换错误
