Manual Dropbox File Processing via API

# Adobe API Wrapper

See Adobe documentation:
- {{ $env.API_BASE_URL }}
- {{ $env.API_BASE_URL }}

In short, this workflow does the following steps :

- Authentication
- Upload an asset (pdf) to adobe
- Wait for the asset to be processed by Adobe
- Download the result

## Credential

Credentials are not "predefined" and you'll have to create 2 custom credentials, detailed in the workflow.

## Result

The result will depend on the transformation requested. It could be 1 of various files (json, zip...) accessible via download URL returned by the workflow.

Workflow can be tested with a PDF filed fetched with Dorpbox for example or any storage provider.
