Create a function to find replacement level based on the team's depth

1	create_roster_replacement_fn(replacement_depth, positions, pbp_type)

`replacement_depth`	Number indicating which rank on team's depth chart the replacement level can at most be.
`positions`	String indicating which position(s) to find the replacement level for, can only be (1) "QB", (2) "RB", (3) "WR", (4) "TE", or (5) "FB".
`pbp_type`	String indicating which type of performance to use, either use (1) "pass" or (2) "rush".

Function that returns a vector of Player_ID_Name values indicating the replacement level for a given play-by-play dataset based on the replacement_depth to decide the team depth chart cutoff, as well as the position(s) to search for, and the type of the play-by-play data that will be used.

# Create the replacement function for QBs using based on 3rd or higher on the
depth chart using passing performance:
find_replacement_QB <- create_roster_replacement_fn(3, "QB", "pass")
replacement_QBs <- find_replacement_QB(model_data_list)
