Mapbox v3

• Try DeckGL v9alpha in case it resolves console errors. It did not.
• For some reason data renders behind Standard style, but renders okay on other styles.
• DeckGL v9alpha is off kilter. Canvas partly appears at top of app. Probably want to revert to v8.
• what is "feature-layer" error at right?
• Are slots needed everywhere actually?

To fix DeckGL v9alpha for Mapbox 3.1, patch line 17 of placemark/node_modules/@deck.gl/layers/dist/es5/text-layer/font-atlas-manager.js with

let _tinySdf;
import('@mapbox/tiny-sdf').then((module) => {
 _tinySdf = module;
});
