get_delta_flex: calculate maxmin distance between points
In benjaminleroy/simulationBands: Conformal Prediction Bands with Simulations

A wrapper of get_delta_simple, get_delta_dist, and get_delta_large relative to the number of observations to be used. Attempts to balance the number of observations vs the fastest approach ( attempting to balance time costs from memory storage and processing speed).

1	get_delta_flex(df, full_breaks = 10, verbose = F)

`df`	data.frame (with only columns that are needed)
`full_breaks`	number of breaks relative to `get_delta_large`, otherwise it's not used.
`verbose`	boolean, a progressbar is provided to track the progress of `get_delta_dist` or `get_delta_large`, if they are used.
