fix: Handle rendering a single point

[khtruong]

SUMMARY

Deck gl scales the x and y axis based on the bounds we pass it. The scaling involves dividing a target size by the range. But since the range is 0 for a single point, we throw an error if our data is a single coordinate. This change will check if we have a single coordinate. If so, then the bounds we pass to deck gl will be the point's coordinates with padding.

TEST PLAN

Manual testing and unit tests.

I tested manually with normal single points, boundary cases, and various viz types. I noticed that it does not render the single point for boundary cases and certain aggregated viz types like hexagon, But I believe this is more of a deck gl issue.
