Reorganize modules

[asenetcky]

Do I even need a modules folder?

I feel like instead of :

project_folder/ └── pipelines └── my_pipeline └── modules ├── my_first_module │   ├── my_first_script.R │   └── my_second_script.R └── my_second_module └── my_first_script.R (forgot to add the .tomls - pretend they're in their respective folders (pipelines/ and modules/)

it should be something like: project_folder/ └── pipelines ├── my_pipeline │   ├── .modules.toml │   ├── my_first_module │   │   ├── my_first_script.R │   │   └── my_second_script.R │   └── my_second_module │   └── my_first_script.R ├── my_second_pipeline │   ├── .modules.toml │   ├── my_first_module │   │   ├── my_first_script.R │   │   └── my_second_script.R │   └── my_second_module │   └── my_first_script.R └── .pipelines.toml
