In addition to the schema, I also want to obtain the parquet metadata (e.g., to get the size of the row groups in the parquet file). Since these are also contained in the footer bytes (the same footer bytes that I pass to readSchema), it should just be a matter of parsing them.

I can currently use the parquetMetadata function from hyparquet to acheive this, but perhaps parquet-wasm can provide a function with the same metadata parsing functionality as well.
