Workspace Method particle_fieldCleanup

Description

Removes unrealistically small or erroneous data from particle fields.

This WSM checks if the input particle field (e.g.
particle_bulkprop_field) contains values
smaller than the given *threshold*. In this case, these values will
be set to zero.

The method should be applied if the particle fields contain
unrealistically small or erroneous data (NWP/GCM model data, e.g.
from the Chevallierl_91l sets, often contain very small or even
negative values, which are numerical artefacts rather than physical
values.)
For the scat_species_XXX_fields, it needs to be applied separately
per Tensor4 type field collection. This allows to use different
thresholds for the different types of fields (not for the different
scattering species, though).

particle_fieldCleanup shall be called after generation of the
atmopheric fields.
