I initially thought no body will ever read a 20GB parquet file over network, but it turns out that many people do -- it's not entirely unreasonable, as we only need to download the portion of the file that is relevant to the query, usually only a few MBs.

Unfortunately, wasm32 is a 32 bit platform, in which the usize is 32 bit, meaning that larger parquet ranges are chopped to 4GB, which leads to incorrect decoding.

We need to fix the upstream object_store to actually fix this. apache/arrow-rs#5351
