-----------------------------------------------------------------
[~wesm], [~apitrou] For our purposes we need to define a custom type and use
arrow CSV reader to parse it. Unfortunately, there is no way to use custom
types with CSV reader right now, because of type dispatch when choosing an
appropriate column builder.
I'm not sure how architecturally it could be solved, maybe custom ColumnBuilder
is a case.
