CSV Export

Implement a new worker to add the CSV export feature. This worker will call arkindex_cli.commands.export.csv.run.

The output_header will not be parametrizable through user_configuration. But all other options should be.

changed milestone to %Arkindex 1.7.1

added P2 label

For the default values in the user configuration, I was going to go with:

    user_configuration:
      element_type:
        title: Type of the elements to export. If none is specified, all elements are exported.
        type: string
        required: False
        default: null
      recursive:
        title: Export child elements recursively. If set to False, only direct child elements are exported.
        type: bool
        required: False
        default: True 
      with_classes:
        title: Export element classes.
        type: bool
        required: False
        default: False
      with_metadata:
        title: Export element metadata.
        type: bool
        required: False
        default: False
      with_parent_metadata:
        title: Export the metadata of element parents with the element.
        type: bool
        required: False
        default: False
      with_entities:
        title: Export transcription entities on elements.
        type: bool
        required: False
        default: False
      classification_worker_version:
        title: Only export classifications created by the specified worker version. "Export element classes" must be set to True.
        type: string
        required: False
        default: null
      entities_worker_version:
        title: Only export entities created by the specified worker version. "Export transcription entities on elements" must be set to True.
        type: string
        required: False
        default: null

This way, by default, all elements of any type under the exported folder are exported recursively, with no additional data.
