Parquet Query Planner: plan byte ranges, pre-fetch in parallel (#75) 
* Parquet Query Planner: plan byte ranges, pre-fetch in parallel.

 - parquetPlan() that returns lists of byte ranges to fetch.
 - prefetchAsyncBuffer() pre-fetches all byte ranges in parallel.
   throws exception if non-pre-fetched slice is requested later.
