feat: add TypeScript definitions (#256)

* feat: build TypeScript definitions and use esbuild for bundling

Inspired by OpenLayers approach.

* chore: switch from Neutrino (webpack) to esbuild for dev server

* chore: use dataurl loader for SVG files, activate minify option for bundle

* chore: watch forever to support Cypress CI tests

* chore: upgrade Cypress

* chore: use localhost for integration test to avoid CORS issues

* chore: rewrite unit test to integration test

* chore: remove unused Jest and update dependencies

* chore: rename GitHub workflow and use Node.js 16

* chore: move config for tools to separate files

* chore: update GitHub workflows

* chore: fix Cypress timeout

* chore: fix website

* chore: run Cypress tests with oldest and newest supported Node.js release

* chore: use dynamic Node.js test matrix

* chore: fix typo

* chore: fix LTS version selection
