Process evaporate options

[ceshm]

Changes:

• Added the prop processEvaporateOptions that allows to transform/modify the evaporate options for each upload

Why?

To be able to upload with different aws configurations (like different buckets) depending on the file attributes (like the type).

Example

processEvaporateOptions={(options: any, file: any) => {
  const fileType = file.type.split("/")[0];
  switch (fileType) {
    case 'video':
      return { ...options, awsRegion: AWS_REGION, bucket: S3_BUCKET };
    case 'image':
      return { ...options, awsRegion: AWS_IMAGES_REGION, bucket: S3_IMAGES_BUCKET };
    default:
      return options;
  }
}}
