ImportError in BrotherQLRaster from PIL _imaging

[stevenlowery011]

When installing via pip and the upgrade flag per the instructions in the readme on a brand new conda environment, a dependency is not installed and results in an ImportError when using the command line tool. The new conda environment comes with Python==3.7.3 and pillow==5.4.1 which satisfies the requirement of pillow>=3.3.0; however, when running the command line tool, an import from pillow fails to be found. After running a pip install --upgrade pillow which installs pillow==7.0.0, the command line tool works.

Can you investigate the pillow requirements again? I suspect that pillow>=3.3.0 is not sufficient anymore.
