Refactor SerializeEntry to handle collections in CsvFeedExporter

[akriger]

Adds the ability to write collections to the CSV. This is especially helpful if you need to write multiple lines for a single Entity (ie. entity that have multiple assets/images)

Summary of Changes

Hello @akriger, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the SerializeEntry method within the CsvFeedExporter to enhance its capability to handle and write collections of data to CSV files. This change is particularly beneficial for scenarios where a single entity needs to be represented across multiple lines in the CSV, such as when an entity has multiple assets or images. The update introduces conditional logic to differentiate between single data entries and collections, ensuring appropriate serialization for each.

Highlights

• CsvFeedExporter Refactoring: The SerializeEntry method in CsvFeedExporter.cs has been refactored to conditionally handle IEnumerable types, allowing for more flexible data serialization.
• Collection Handling: If the input value to SerializeEntry is a collection (and not a string), the _writer.WriteRecords() method is now utilized to write all items in the collection, enabling multi-line entries for a single entity.
• Single Record Handling: For non-collection values, the existing _writer.WriteRecord() and _writer.NextRecord() logic is retained, ensuring backward compatibility for single-entry serialization.
• Dependency Update: The using System.Collections; directive was added to CsvFeedExporter.cs to support the new collection handling logic, specifically for checking IEnumerable types.

Code Review

This pull request refactors SerializeEntry to support writing collections to the CSV file, which is a great addition for handling entities with multiple related items. The implementation is straightforward, but I've identified a couple of potential issues regarding an edge case with char[] and the handling of the cancellationToken for long-running operations. My feedback includes a code suggestion to address these points to make the implementation more robust.

they are, but wasn't sure if they were just suggestions or should be followed
