This function add to the data frame generated by
mapint.H_est. Required columns in input are
find_outlier( epma, phase = everything(), element = everything(), interval = c("prediction", "tukey"), method = c("rq", "lsfit", "median"), percentile = 0.99, fine_phase = NULL )
A value returned by
A type of the interval. Data points outside intervals are treated as outliers.
A percentile of predictive interaval.

When comparing data points of spot analysis and mapping analysis who share the same coordinates, it is expected that they analyze the same phases. However, this is unlikely when mapping analysis involves multi-phase pixels due to sizes of pixels and phases. This function removes such multi-phase pixels by finding outliers of mapping peak intensities.
