[dsgallups]

• [x] I agree to follow the project's code of conduct.
• [x] I added an entry to CHANGES.md if knowledge of this change could be valuable to users.

• Updated variant Error::FeatureHasNoGeometry to wrap a Box<Feature> instead of a Feature. This reduces the size of the enum from 200 to 48.
• Fixed document indentation.
