Wang et al. [2016] particle size distribution for rain.

Reference: Wang et al., Investigation of liquid cloud microphysical
properties of deep convective systems: 1. Parameterization raindrop
size distribution and its application ..., 2016.

This is a 1-parameter PSD, i.e. pnd_agenda_input shall have one
column and pnd_agenda_input_names shall contain a single string.
The input data in pnd_agenda_input shall be rain mass content in
unit of [kg/m3]. The naming used is pnd_agenda_input_names is free
but the same name must be used in particle_bulkprop_names and

Particles are assumed to be near-spherical, ie. psd_size_grid can
either be in terms of volume (or mass) equivalent diameter or
maximum diameter.

Derivatives are obtained analytically.

The validity range of mass content is not limited. Negative mass
contents will produce negative psd values following a distribution
given by abs(RWC), ie. abs(psd)=f(abs(RWC)).

If temperature is outside [*t_min*,*t_max*] psd=0 and dpsd=0 if
picky=0, or an error is thrown if picky=1.
