Teensy 4.0 PORT manipulation to read/write data to multiple pins

[MakerBR]

I have noticed that lot of people been asking about port manipulation example code and I was also searching for the same. After reading some documentation I came up with these program to read/write multiple pins simultaneously at faster speed.
This is my first attempt at creating something like this. Let me know how it is.
Here is the GitHub link: https://github.com/ManojBR105/Teensy...lel_read-write
Please see readme file for more information.
I have used only pins 0-23 and optimized the code to take less time and operations to the best of my knowledge.
