Pre-bundling map-interface dependencies

[falseinput]

Hi,

thanks for your work on this project!

I wanted to try out MapGrab to write tests for https://github.com/falseinput/geogrid-maplibre-gl, but when I imported
the map interface via script tag I got:

Uncaught TypeError: Failed to resolve module specifier "tslib". Relative references must start with either "/", "./", or "../".

map-interface is exported as ESM module, so theoretically it allows me to use it without a bundler, however @mapgrab/map-interface/index.esm.js imports dependencies like the tslib explicitly. In other words: dependencies are not pre-bundled.

To get it work I had to use JSPM Generator to generate import maps:

<script type="importmap">
    {
      "imports": {
        "@mapgrab/map-interface": "https://ga.jspm.io/npm:@mapgrab/[email protected]/index.esm.js"
      },
      "scopes": {
        "https://ga.jspm.io/": {
          "@mapbox/point-geometry": "https://ga.jspm.io/npm:@mapbox/[email protected]/index.js",
          "@mapgrab/map-interface-types": "https://ga.jspm.io/npm:@mapgrab/[email protected]/src/index.js",
          "@mapgrab/map-locator": "https://ga.jspm.io/npm:@mapgrab/[email protected]/src/index.js",
          "@turf/bbox-clip": "https://ga.jspm.io/npm:@turf/[email protected]/dist/esm/index.js",
          "@turf/helpers": "https://ga.jspm.io/npm:@turf/[email protected]/dist/esm/index.js",
          "@turf/invariant": "https://ga.jspm.io/npm:@turf/[email protected]/dist/esm/index.js",
          "@turf/meta": "https://ga.jspm.io/npm:@turf/[email protected]/dist/esm/index.js",
          "tslib": "https://ga.jspm.io/npm:[email protected]/tslib.es6.mjs"
        }
      }
    }
</script>
<script type="module">
  import * as MapInterface from "@mapgrab/map-interface";

  // ...
</script>

While this works, I had spend some time trying to figure it out. The way import maps work or the fact they exist is not yet well known in general.

Pre-bundling this package would be great, because it would just allow to import as a module without extra steps.

Btw. I was trying to make a PR, but map-interface is a submodule and I could not clone it.
