[Showcase] Vue version & implementation example

Hello,

This is a great library & I've already gotten a Vue wrapper called [`v-maplibre`](https://v-maplibre.geoql.in/) which has tons of layers - the default maplibre-gl-js, plus deck.gl ones as well as custom layers like [`maplibre-gl-lidar`](https://github.com/opengeos/maplibre-gl-lidar)

I was able to add `deck.gl-raster` as well in my [`mapcn-vue`](https://mapcn-vue.geoql.in/) package which exports styled components for `shadcn-vue` packages - https://mapcn-vue.geoql.in/examples/deckgl-landcover and https://mapcn-vue.geoql.in/examples/deckgl-cog
