Review comment:
Chatting with @tflobbe on this - Can we improve the API to not expose `fieldName/fieldValue` pair and just ask the user to enter one input?
For example could we take either of these two approaches
1. Use an `_internalFeature` field. The `fieldName` that the user defines would be used as the `featureName` in the FeatureField ctor . So internally everything is stored in one field.
2. Every feature gets is own field - so the user only defines the `fieldName` and we use the same value as the `featureName`
Approach 2 would definitely lead to lots of fields. But maybe it's worth exploring 1 and seeing if that helps improve the API without trading any performance.
