Added the easily fixed stuff that shouldn't need discussion

[abodeuis]

This PR is the easy fixes that are just getting stuff functional.

All Fixes were only to Polygon Feature results

• Renamed PolygonLegendAndFeauturesResult to PolygonLegendAndFeatureResult to correct spelling
• Added "label" field to PolygonLegendAndFeatureResult
• Fixed type of legend_bbox field to actually be able to send bounding box data
• For all optional fields added = None or default=None so that this doesn't have to be specified in the constructor.
• Cleaned the formatting of PolygonLegendAndFeatureResult up a bit and added some descriptions.

Hopefully these parts at least can be merged immediately as they are just fixes and shouldn't need discussion

Only thing I'd push back against is the renaming to PolygonLegendAndFeatureResult instead of PolygonLegendAndFeaturesResult. I believe we could keep the plural form to ensure folks know this stored multiple feature features in one result. @marshHawk4 thoughts?

Create a 2 point bounding box and a polygon bounding box field for legend bounding boxes

[abodeuis]

I left legend_bbox as a 2 point bounding box and added legend_contour field which will be the polygon bounding box. @marshHawk4 Should be ready for a merge if you want to go ahead and review

[marshHawk4]

Maybe add in example like [x_min, y_min, x_max, y_max]
Since the order of these matter and I have seen other formats for bbox that are not this exact one.

PolygonLegendAndFeatureResult needs to be PolygonLegendAndFeaturesResult
