MapLibre implementation of video tiles

[fgassert]

Implements a Maplibre native version of video tiles as a custom Source derived from RasterTileSource.

I played around a bit trying to improve the performance of the Deck.gl implementation and learned a few things:

• Deck.gl layers don't work well in globe view because the path/polygons don't align with the maplibre globe. You can make it work but performance is terrible.
• You can pass videoframes directly to deck.gl/maplibre saving memory and cpu cycles.
• A decoder queue ensures that tiles load correctly. (Firefox fails with too many parallel decodes, complaining The given encoding is not supported.).
• Firefox performance is better than Chrome?
• Can't set maxTileCache per-source in Maplibre. Only on the base map object? Too many cached tiles affects performance.

There are some hacks to get typescript to not complain. I don't know if this is normal since I don't usually work in typescript.
