feat: Google indentation + more configurable parameters

[nyoungstudios]

• makes Google indentation 4 spaces (with the option to change it on the cli or for any other output format style)
• adds the ability to skip adding empty parameters, raises, or returns with cli flag
• adds .idea to .gitignore for pycharm users
• adds missing : to when adding the raises for Google docstring format

Fixes issue: https://github.com/dadadel/pyment/issues/18

Thank you for your elaboration. I would like to clarify that I am not a manager of this repository in any way, I just like the software, and thought if I perform some code reviews on pull requests, that they might be merged sooner. I do not have the authority to merge. I don't believe it is my position to judge whether any tests or documentation should be updated. In this point in time, I did not find any tests or documentation that should be updated based on your changes.
