Initial Parquet File/Dataset abstraction (#501)

Prep work for being able to fetch metadata from a bunch of Parquet files
in a folder and load a spatial filter

### Change list

- New `ParquetFile` and `ParquetDataset` Rust structs to read from one
or multiple Parquet files. This is generic over `AsyncFileReader`, which
primarily works with object store.
- Added initial metadata handling, to e.g. read the bounding box of the
file.
- Added Python bindings to each class. This uses ObjectStore.
- Added initial JS bindings to each class. This uses a custom
implementation of `AsyncFileReader` [vendored from
parquet-wasm](https://github.com/kylebarron/parquet-wasm/blob/0ecad6e1d87a377051087122f7ee2db52a2d6533/src/reader_async.rs).
I couldn't get the ObjectStore integration working just yet. Thought
object_store_wasm_s3 was updated and that might be an interesting thing
to check out.
