Review Comment:
   Thanks for reviewing. I will try to make the name change to align with 
Parquet annotation The only thing is that we need to have separate type ID for 
ltz/ntz and micro/nano seconds. so it would be cleaner to have them into 
separate entries rather than grouping them with parameter.
