Determine the duration of effect for each treatment

determine_Effect_Duration(
  XY,
  colname_deriv1 = "pred_gam_deriv1",
  colname_ref_deriv1 = "base_pred_gam_deriv1",
  diff_threshold = -1e-04,
  grid_n = 1000,
  auto_round = TRUE,
  round_to = 4
)

`XY`	data.frame with times and original-scale tumor burdens, etc., for each of several identifiers. Typically this is from the cleaned output data of maeve::model_study().
`colname_deriv1`	character name of column with first derivative from GAM model fit.
`colname_ref_deriv1`	character name of column with first derivative from specified reference group of GAM model fit.
`diff_threshold`	numeric threshold to differentiate from zero, i.e., values below this are treated as zeros in evaluating changes.
`grid_n`	numeric number of equally spaced grid points across which to approximate the effect duration.
`auto_round`	logical: automatically round results to "round_to" digits?
`round_to`	numeric number of digits to which the effect duration should be rounded.
