feat!: extract advanced layers & sources into separate bundle

[silvester-pari]

This PR splits up OpenLayers formats, layers and sources to include only the most basic ones, while advanced ones can be added as a separate plugin. This is in order to reduce the bundle size for the most common use cases.

Before

After

Included in the base bundle:

• Formats: GeoJSON, MVT
• Layers: Group, Image, Tile, Vector, VectorTile,
• Sources: ImageWMS, OSM, Tile, TileWMS, Vector, VectorTile, WMTS, XYZ

Usage

In order to use all formats, layers and sources provided by OpenLayers, import the plugin as well:

import "@eox/map/dist/eox-map-advanced-layers-and-sources.js"
import "@eox/map/dist/eox-map.js"
<eox-map [... GeoTIFF sources, STAC layers etc ...]></eox-map>

If the developer forgets to import the bundle but tries to use an advanced format, layer or source, a console error is thrown:

Closes #495

Interesting technique. I'm curious to find out if this directly affects the bundle size of the AgriApp, one of our downstream applications.
