getSpiralPlot

This utility function yields a spiral plot based on
phenological dates estimated from a polygon.

Provides functions and methods for estimating phenological dates (green up,
start of a season, maturity, senescence, end of a season and dormancy) from (nearly)
periodic Earth Observation time series. These dates are critical points of some
derivatives of an idealized curve which, in turn, is obtained through a functional principal
component analysis-based regression model. Some of the methods implemented here are
based on T. Krivobokova, P. Serra and F. Rosales (2022) <https://www.sciencedirect.com/science/article/pii/S0167947322000998>.
Methods for handling and plotting Earth observation time series are also provided.
