PIL is also a dependency

[guruthree]

Setting up a conda environment, I noticed that PIL is also required, but not listed in the requirements.

For reference, to setup a conda environment for deepsaber:

conda create -n deepsaber
conda activate deepsaber
conda config --add channels conda-forge
conda install numpy pytor librosa panda matplotlib pillow

Conda's ffmpeg didn't work for me though, so in level_generation_utils.py I had to explicitly set it back to the system ffmpeg in /usr/bin/ffmpeg. For how ffmpeg is used there I suspect oggenc (from vorbis tools) could be used instead, which wouldn't be co-opted by conda.

Super helpful, thanks, about to do just this.
