Update_pypi_package

[SantosJGND]

Hello,

I would like to integrate this script into a project i am working on. However i would like to add single vcf output option, perhaps optimally have it as a pypi package (the setup.py format is outdated).

Wondering if you have any maintenance on this project? If it would be alright if i develop on it? Would you like to be added as contributer?

PS: it is a publicly funded open-source project.
Best,
Joao
