   I'm trying to use the parquet RLE and delta binary encoding for some of my 
columns.  I dont want them to use dictionary encoding at all.  However, when I 
try to set my builder to disable dictionary / enable RLE or delta binary, I hit 
this exception:
   "Selected encoding is not supported".
   
   Looking in parquet/encoding.cpp MakeEncoder it looks like these encodings 
arent actually supported.  Am I going about this the wrong way, or am I bound 
to encode with dictionary or PLAIN?
