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

[izumigoto]

Hey there! @huangsam
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.

Hence i would like to contribute 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

Closing #118 as I sense the thing that could have been done in that case is just adding more docstring content about the different modes. If you still find this issue to be interesting, please reopen this. Thanks again for contributing to Ultimate Python!
