Add constraint for requested players #3
Description
It would be nice if a list of players could be selected that would be included in the lineup.
For example, tonight's multigame lineup doesn't include McDavid, which outside of the solver sounds like a poor idea. This could be implemented with a new column for "requested" and give the player values a 1.0, and the constraint would just make sure that the number of requested players equals the amount in this column. This might need a bit of tweaking, because requesting too many players could result in an unsolvable team.
Something like:
python dfs_solver.py rawdata/<whatever> request="Connor McDavid,Leon Draisaitl"
