> ColumnWriter::RleEncodeLevels' size estimation might be wrong

> The size estimation might be too small. Instead of adding a factor of 2
> (which I guess we're off), we should add a call to LevelEncoder that
> redirects either to RleEncoder::MaxBufferSize or computes the value for the
> BitPacked encoding.
