Setup a Sersic mass and light profiles.

Parameters
----------
centre: (float, float)
    The (y,x) arc-second coordinates of the profile centre.
axis_ratio : float
    Ratio of profiles ellipse's minor and major axes (b/a).
phi : float
    Rotational angle of profiles ellipse counter-clockwise from positive x-axis.
intensity : float
    Overall flux intensity normalisation in the light profiles (electrons per second).
effective_radius : float
    The circular radius containing half the light of this profile.
sersic_index : float
    Controls the concentration of the of the profile (lower value -> less concentrated, \
    higher value -> more concentrated).
mass_to_light_ratio : float
    The mass-to-light ratio of the light profile.
mass_to_light_gradient : float
    The mass-to-light radial gradient.
