Problems on the execution of BaseHandwrittenPostprocessor

[RosiYo]

When using the code provided in this documentation, but replacing the NullPostprocessor with a BaseHandwrittenPostprocessor, two errors arise due to default augmentations applied by the handwritten postprocessor.

1. Scribbles Augmentation (scribbles.py, Augraphy)
   The scribbles augmentation attempts to use random fonts, which causes a file-writing error if the required fonts directory does not exist. I resolved this by manually creating the fonts directory beforehand.

2. Ink Generation (inkgenerator.py, Augraphy)
   In the generate_noise_clusters function of the InkGenerator class, the std_range values must be explicitly cast to int before being passed to random.randint. Otherwise, a type mismatch error occurs.

I don't know whether these issues should be addressed within this library or reported upstream to Augraphy. Regardless, here’s the code that triggers the errors:

model = BaseHandwrittenModel()
postprocessor = BaseHandwrittenPostprocessor(rng=random.Random(42))
compositor = DefaultCompositor(postprocessor)
renderer = BitmapRenderer()

# Assume `raw` is a string containing MusicXML data
scene = model(data=raw, format=".musicxml")
compositor.run(scene.pages[0].view_box, dpi=120)
renderer.render(final_layer)
