Feature Request: Add pyproject.toml

[EmperorArthur]

Underlying Issue

The project uses the old requirements.txt format instead of the modern "pyproject.toml" file.

Use case

I would like to install this as a python package. Which is much easier than having to manually pull everything down, make sure the requirements.txt is installed, then having to link the program manually to my bin folder.

pip install git+https://github.com/MightyCreak/diffuse.git

Users like me are forced to use windows for work / gaming, and would like to take advantage of this project without having to jump through hoops.
