Cloudinary的上传方式

又在写一个新的插件，

上传用base64

https://cloudinary.com/documentation/upload_images

base64上传

https://cloudinary.com/documentation/upload_images#upload_via_a_base_64_data_uri

option的字段来自api，参见

https://cloudinary.com/documentation/image_upload_api_reference

测试用的命令

rsync -avrP --exclude "node_modules" ".github" .  ~/.picgo/picgo-plugin-cloudinary/

一些注意的地方

base64，需要拼接，然后extName获取图片格式。再拼接，

文件名只用md5，不添加extName到public id处
