Add support for pyproject.toml

The same functionality should work, but you would just have to skip to only the "[dependencies]" section in pyproject.toml.

I would also really like to see support for pyproject.toml in pur as I really like the development cycle pur enables, and is using / have used it in a bunch of projects.

Since many things have changed wrt. how dependencies are managed in Python, I am not sure that supporting pyproject.toml in pur necessarily makes sense? Anyway I wrote a small spiritual successor to pur you can check it out here: https://pypi.org/project/uppd/.

I am curious - is this something that would ever be supported? I see this has been open for quite some time.

A lot of our updating is done using pur and we really don't want to swap libraries.

Most likely yes, if I find a day when I'm wanting to code on something. If you need it sooner please submit a PR and I'll review it.
