Description: Computes the maximal fat oxidation (MFO), the exercise intensity
    that elicits it (Fatmax), the Fatmax zone and the crossover point from
    indirect calorimetry data of a graded exercise test. Substrate oxidation is
    estimated with the stoichiometric equations of Frayn (1983)
    <doi:10.1152/jappl.1983.55.2.628>, Peronnet and Massicotte (1991, Can J
    Sport Sci 16(1):23-29) or Jeukendrup and Wallis (2005)
    <doi:10.1055/s-2004-830512>, and Fatmax is located with a third- or
    second-degree polynomial, the measured values or the MRER method. Fat oxidation kinetics are described with the SIN model of
    Cheneviere et al. (2009) <doi:10.1249/MSS.0b013e31819e2f91>, which returns
    dilatation, symmetry and translation, together with the intensity at which
    fat oxidation becomes negligible (Fatmin). Applications of these methods
    are given in Achten et al. (2002) <doi:10.1097/00005768-200201000-00015>
    and Montes de Oca et al. (2021) <doi:10.1080/17461391.2020.1788650>.
