Add module docstring to c stub

[pazzarpj]

Porting the python docstring over to the c stub output is handy for maintaining even more documentation synchronization.

Eg.

"""
This module is developed for adding new functionality to upython
   We want tabs
"""

Should translate to

/*
This module is developed for adding new functionality to upython
   We want tabs
*/

There could be a case for adding ustubby generic output to the generated file so that the source is not lost

/*
This module is developed for adding new functionality to upython
    We want tabs

    This file was auto-generated using uStubby.
    Please see https://github.com/pazzarpj/micropython-ustubby

Put Python module description to C code

TODO: Put the module description from the C code into the target compiled micropython module.
DESCRIPTION in sourse stub module.py -> uStubby -> DESCRIPTION in module.c ->micropython make -> DESCRIPTION in target module.DOC

The target compiled module should have a 'DESCRIPTION' like stub modules from the zip with using the help() command:

>>> import module_description_1
>>> help(module_description_1)
Help on module module_description_1:

NAME
    module_description_1 - This is one-line description of module.

FUNCTIONS
    example() -> None
        no matter here

FILE
    d:\owl\sova\python_source_code\esp32_server\ustubby\module_description_1.py

and

>>> import module_description_2
>>> help(module_description_2)
Help on module module_description_2:

NAME
    module_description_2

DESCRIPTION
    This is multi-line description of module.
    This is multi-line description of module.

FUNCTIONS
    example() -> None

Hi Ihor,
I'm not sure how to compile the help into the c extension.
The original intent of this module was to use the type annotated python and run something like OpenAPI across it to generate the documentation for the modules.
