Iterate once in Frame.ofRowsOrdinal #396

Closed zyzhu closed 5 years ago

zyzhu commented 5 years ago

I've followed the issue https://github.com/fslaborg/Deedle/issues/356 and discussion https://github.com/fslaborg/Deedle/pull/357 to avoid iterating twice in Frame.ofRowsOrdinal

Ping @kflu and @tpetricek for review
