getValuesWindow

Modified R Code from raster package raster::getValuesFocal.
Returns one row per pixel, which contains the values
of the pixel neighborhood that is defined by the size of the window.
The size of the window is defined by the window side length (wsl).
The window is centered on one specific pixel.

Spatial structural diversity refers to the spatial, i.e.
horizontal arrangement of landscape elements and can reveal itself as
landscape features, such as patches and linear features. The 'R' package
'StrucDiv' provides methods to quantify spatial structural diversity
in continuous remote sensing data, or in other data in raster format.
Structure is based on the spatial arrangement of value pairs. The 'R' package 'StrucDiv'
includes methods to combine information from different spatial scales, which allows to quantify
multi-scale spatial structural diversity.
