v0.5.1

Mainly some additions to improve the development cycle for seedir:

Added

• GitHub workflows for testing the code (on pushes and pulls to main and dev) and for uploading to PyPI (on new release).
• Created a pyproject.toml
• Add CONTRIBUTING.md for instructions on how to contribute to the project

Changed

• seedir.fakedir.fakedir_fromstring has been refactored. The logic is essentially the same, but there have been some simplifications and more comments have been added.
