Switch dependencies to pyproject. Some fixes with that

[Onder7994]

Hello! I add dependency control via poetry. This is more convenient. And any can install code like this

pip install "git+https://github.com/vladko312/SSTImap.git#branch=master"

And code will installed with entrypoint script - sstimap.

You can check it

poetry install
poetry run sstimap

Build and install localy

poetry install
poetry build
pip install dist/sstimap-1.3.1-py3-none-any.whl
sstimap

Chek on my fork repo

python3 -m venv .sstimap
source .sstimap/bin/activate
pip install "git+https://github.com/Onder7994/SSTImap.git@feature/pyproject"
sstimap -h

This is a good idea! I also considered making a python module, but with a way to use both as a proper module and as a tool.
I delayed that update, as I want to make some changes to the architecture before that.

For now, I will not merge this request, as it has some issues. For example, it ONLY works as module, as it obtains the version info from the module. This will prevent SSTImap from being used as a standalone tool, as well as installing multiple versions at the same time.
I might merge it later after fixing some things and changing the architecture.

Also, can you provide more details about other changes? E.g. why os-based file and directory access was replaced by pathlib?

Thank you for you answer!

I move to pathlib, because this is more convenient with poetry. Old way with sys.path does't work any more, for my opinion pathlib versatile and easier.
