changed XPT metadata reader to no longer read full dataset and instead read only header, 1 row, and end of file to estimate rows.
Works for edge cases --empty dataframe and small row size. I can provide these datasets to the reviewer as github does not support XPT files and thus I cannot attach them to the PR.
