add_xpass

Build columns from the expected dropback model. Will return
<code>NA</code> on data prior to 2006 since that was before NFL started marking scrambles.
Must be run on a dataframe that has already had <code>clean_pbp()</code> run on it.
Note that the functions <code>build_nflfastR_pbp()</code> and
the database function <code>update_db()</code> already include this function.

A set of functions to access National Football
League play-by-play data from <https://www.nfl.com/>.
