This seems like a bug in the parquet-go library, we should have roughly 8KB pages this is the case for level 0 property like TimeNanos or SeriesRef but not for repeated and nested values.

Turns out the problem is that we actually read ALL pages and skip them after, we should leverage the PageReader.SeekToRow() to only read what we need to.
