8ba13f44d5 Remove unnecessary copy
Now the `== 'Dawson Creek'` query is ~210ms, which is approx the
same as a `count(*)` query. This seems maybe OK, since the row group
filter is only excluding 30% of records.

92ba5f94e0 reuse FileMetaData
For the statscan dataset, parsing the file metadata takes ~30-40ms,
so stash it away for future re-use.
