Review Comment:
   CI just failed for `ArrowReaderTest > testReadAll()`. 
   
   Generic reader and writer expects byte[] based UUID handling and internal 
reader and writer works directly on UUID object. So, we do need a factory 
method here as we need to supply different kinds of UUID representation.
