Threshold data using the elbow method

1	get_elbow_threshold(xvals, yvals, upper_plateau = FALSE)

`xvals`	X values
`yvals`	Y values
`upper_plateau`	If `TRUE`, instead of connecting the first and last data points, the left support is chosen such that no points are above the line. This is useful if there are a few outliers with very low X values.

The threshold, i.e. the value of the X axis where the distance between the Y value and the line connecting the first and last points is maximal.
