The following classes should be accessible from R:
* class DataSource
* class DataSourceDiscovery
* class Dataset
* class ScanContext, ScanOptions, ScanTask
* class ScannerBuilder
* class Scanner
The end result is reading a directory of parquet files as a single stream. One
should be able to re-implement [https://github.com/apache/arrow/pull/5720] in R.
