Provide a document exporter

Problem/Motivation

As YAML Form elements get more complex, developers may need to export the raw submission data as JSON, YAML, or XML.

Proposed resolution

Provide a document exporter which creates JSON, YAML, and XML documents for submissions in a zipped archive.

Notes

• Document file names will use token
• Each document will contain the serializes YamlFormSubmission::toArray(TRUE) output.
• Not sure what meta data needa to be added the export.

Remaining tasks

• Add entityStorage to YamlFormExporter plugin as dependancy
• Add columns=TRUE to YamlFormExport annotation
• Convert FileHandleBaseYamlFormExporter to FileHandleYamlFormExporterTrait
• Create TabularBaseYamlFormExporter
• Move getFieldDefinitions() ADD CACHING
• Move getElements() ADD CACHING
• Move buildHeader
• Move buildRecord
• Create DocumentBaseYamlFormExporter
• Hide most options for data export if columns = FALSE.
