Use minimal parquet-wasm build for bundle size

We currently use the default parquet-wasm build, which gzipped is 1.4MB. If we use a minimal parquet-wasm build with only the `reader` and `zstd` features, we can get down to 709KB. If we additionally use brotli compression, we can get down to 491K. Then we can use https://github.com/foliojs/brotli.js to decompress it on the frontend.
