   This will be somewhat trickey @feniljain  
   
   If there is a single file in the parquet scan, it should be simple
   
   If there are multiple parquet files it will take some more thought,. 
   
   It also won't be possible when there are pushed down predicates. To support 
that case I think we would have to implement offset in the parquet reader 
itself (in arrow-rs)
