Migrate requirements/ to pyproject.toml #42
Description
🐞 Problem
The reason behind having a requirements/*.txt is that dependabot was only capable to parse dependencies within this sort of files. However, support for pyproject.toml was recently introduced, meaning that extra dependencies can be specified in the Python project file.
💡 Implementation
In addition to the migration of the requirements, the tox.ini file needs to be updated. Although the implementation of #41 will not use Tox, this file turns out to be useful locally, as it unifies different commands locally.
