Attachment module documentation

describe

The attachment system currently provides AWS S3 object storage service, using the default IAM account for read and write operations;

###Instructions for use

Initialize attachment system

// Initialize the accessory system, the platorm configuration is as follows, for reference
const PLATFORM_CONFIG = {
    AWSS3: 'awss3', // key replace with uuid
    ALIYUN: 'ailiyun',
};

// It is recommended not to pass the platform type for initialization, AWS S3 is used by default
import { upload, multipartUpload } from '@toeverything/components/attachment';
