Support 1.18 and newer chunks in examples

[TaylorDale]

When I run the chunk decoding example in clientInternal.js on a 1.18 server the chunk provider stays blank. Stepping through the code executing it seems like packet.sub_chunk_count === -1 which causes most of the code in networkDecodeNoCache() to be skipped.

This line is also getting called in ChunkColumn.js which is causing unintended console output, not sure if it is of any relevance:
console.debug('[wp] Read ', extra, 'bytes')

Caves and cliffs update chunks are not currently supported in bedrock-provider

Got it, cheers 👍

Would it work with the updated latest version of bedrock-provider?

(assuming that CI actually worked with it)

The breaking change with bedrock-protocol 3.0 is move of chunk implementation into prismarine-chunk. 1.18.30+ is not supported per issue in pchunk PrismarineJS/prismarine-chunk#182
