   ## Which issue does this PR close?
   
   None
   
   ## Rationale for this change
   
   I noticed that with the current default parquet writer settings, writing a 
single row to a parquet file results in a file over 4MB in size. Some of the 
config values are being set to explicit values (e.g. plain encoding) rather 
than the default setting in the `parquet` crate which is to leave these values 
as `None`. 
   
   ## What changes are included in this PR?
   
   This PR makes the session level default for these values `None` to match the 
behavior of the `parquet` crate. After doing so, parquet files are now a 
minimum of 4KB rather than 4MB.
   
   ## Are these changes tested?
   
   Yes by existing tests.
   
   ## Are there any user-facing changes?
   
   Better default parquet writer settings
