General improvements

[chfour]

I made some changes and corrections, mainly to the Python side of the source code.
The changes include:

• Adding live webcam input to videoToTextColor.py! Use cam:[webcam_index_here] as the input file. (cv2.VideoCapture() also takes integers, which correspond to webcam indexes)
  
• Re-indenting from 2 spaces to the standard (recommended) 4 spaces
• Renaming variables to match Python recommended naming conventions
• Syntax corrections and function docstrings
• Changing all %-format strings (old) to Python 3 f-strings
• Changing all double-quoted strings to single-quoted ones
• In videoToTextColor.py, importing convert_img() from imgToTextColor.py
• Adding a .gitignore to make git ignore temporary files
• Adding a requirements.txt file with required pip modules (installable with pip install -r requirements.txt)
• Removing an unnecessary import

As a side note, this whole idea with compression based on Markov chains and Huffman trees is genius. The video was awesome too, as always :)

Haven't tested code, but the changes to more standardised code styles and other similar small improvements LGTM!

seen your code, another suggestion is to grab the aspect ratio of the video/image instead of hardcoding to 16:9

also, the width of 80 hopefully can be changed by CLI or config file

the code worked for my side

OS Version: Windows 11 for Workstations 22H2 22572.100
Python version: 3.10.2

That could definitely be done with something like ffprobe-python, I'll try to implement it as soon as I have some free time

also, the width of 80 hopefully can be changed by CLI or config file

I'll implement that using shutil.get_terminal_size()

btw, i formatted your code to flake8 standard, as a poll request
