Secsie-conf

In this release, I added type support for `PathLike` type params in the `parse_config_file` and `generate_config_file` functions.

Corrected classifiers

Added badges for PyPi deployment and unit tests in README.

In this version, I added support for lists.

Lists are a set of comma separated values in an attribute declaration. Here is a valid example of a list:
ini
list = this, that, 42

This will be parsed into `['this', 'that', 42]` in Python. For more info read the README.

Fixed a bug where `generate_config` was not okay with not having an `output_file` decalred.
