Automatic altitude/radius parsing

Kepler.gl does some pretty smart things with CSV.
For example, if my CSV looks like this:

```
fooLat,fooLng,fooRadius,barLat,barLng,barRadius
```
Kepler will automagically create two points layer named "foo" and "bar" with the correct columns set for lat/lng.

It doesn't seems to parse fields like radius and altitude and fill them automatically

No files or tests are named. Start by locating the CSV import and field-inference entry points, then trace how latitude and longitude fields create point layers. Done means CSV fields such as fooRadius, barRadius, altitude, and similar values are recognized and populated automatically without breaking the existing lat/lng behavior.
