Add feature for indented code

[AndreasLuckert]

It'd be nice if the tool could recognize two things:

1. Language-specific horizontal ruler-extension limits defined in the settings.json - file:

   "[python]": {
       "editor.rulers": [
           80,
           120
       ]
   }

2. Indentation according to current code: Instead of heaving to tab it over and then accept that the ruler exceeds the vertical limits like so ...

   # ------------------------------- Some function ------------------------------ #
   def func():
   
   # ------------------------------- Sub-function ------------------------------- #
   def sub_func():
       pass

... it'd be awesome of the extension calculated automatically the difference between the indentation and the vertical right limit, which would lead to following result:

# ------------------------------- Some function ------------------------------ #
def func():

    # ----------------------------- Sub-function ----------------------------- #
    def sub_func():
        pass
