[Bug] geoJSON points not loading

[ford-scoop]

Describe the bug
I am trying to upload geoJSON files that include just a single Feature that is a Point, but am getting a Failed to upload files error.

To Reproduce
Steps to reproduce the behavior:

1. Go to kepler.gl/demo
2. Try to upload this geoJSON snippet (as a .geoJSON file):

{
	"type": "Feature", 
	"geometry": {
		"type": "Point", 
		"coordinates": [
			41.8817441, -87.6335398
		]
	}, 
	"properties": {
		"lat": 41.8817441, 
		"lng": -87.6335398, 
		"icon": "place"
	}
}

This results in a Failed to upload files error.

Expected behavior
It is expected the file uploads and the Point appears on the map.

Desktop (please complete the following information):

• OS: macOS 10.15.4
• Browser: chrome
• Version: 83.0.4103.116

Additional context
This process worked as recently as mid-late May, so I believe a recent release may have broken it. Other geoJSON files that I upload work, though they are all either FeatureCollections or MultiLineStrings.

I also tried to use the examples in the docs. The single Feature also failed, while the FeatureCollection uploaded as expected.

Thank you!

Fix is coming up, for now, use feature collection to wrap single feature.
Thanks

Awesome, thank you! Will do that for the time being :)
