Finds binding targets given list of dataframes containing binding info for effectors

find_targets(
  aList,
  column = "max_score",
  by_rank = FALSE,
  n_targets = 2000,
  threshold = NULL
)

`aList`	the result of running score_targets
`column`	column name used in either ranking or thresholding the possible targets
`by_rank`	if TRUE will return top n_targets; if FALSE will use thresholds
`n_targets`	the number of targets to return for each effector if by_rank=TRUE
`threshold`	threshold to use if by_rank=FALSE
