   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   The more filtering that can be pushed to the parquet reading, the faster a 
query will run in general as less work is needed to decode and process data 
that will eventually be filtered from the plan
   
   There are several ongoing workstreams that will eventually lead to pushing 
down substantial additional filtering into the parquet scan that should 
substantially increase performance for datafusion. I wanted to capture them 
here to provide more visibility
