Review comment:
I thought a little more about this and decided to go with your original
suggestion. Now I think it is actually not a bad idea to expose a little bit of
complexities inside `ParquetWriter` here to give a signal to the user that
`rowGroupSize` is actually used for block-size setting too (and there is a
comment too, so that should be fine).
PTAL.
