chore: add a bench and render tests for tesselation

[CommanderStorm]

I used claude to add one tesselation benchmark and respective render tests.

Because we currently just ignore the extra tesselation (in fact, we currently ONLY have tesselated render tests) adding this is worthwile anyhow.

Also slims the tesselation PR a bit.

need to be reencoded using the rust encoder because otherwise they are very weird (early java enoder I guess) and also not a good benchmark in comparison to the smaller, tesselated tiles

It looks like there's a problem reading the updated tile, I'm guessing it's a bug in the ts version of the mlt parser.
Let me know how I can help. Once CI passes this can be merged.
