to add new codes for file access modes in (advanced/file_handling.py

[izumigoto]

python file handling expands not only to text files but binary and csv files too! and many more - a important feature of python which can scrap data across different files. and that's why the the knowledge to know about all the file handling modes in python makes the learner more of a prominent coder.

contributed to (advanced/file_handling.py) inserting r+(read and write),w+(write and read),a+(append and read),binary file modes rb,wb,rb,rb+,wb+ etc and the same for csv files with these modes

Thanks for creating this PR but I sense that these options can be added to the docstrings of other existing methods in this module. Closing this PR for now, but feel free to create another one in the future
