feat: add a board.txt file generation script

[swishswish123]

Hello!

in order to run this code with your own printed board, I need to create my own .txt file of the board.

Even though I have managed to create my own txt file it doesn’t seem to be detected here so I was wondering if there’s a way that would automatically generate the txt file or a way that we don’t need to add the txt file (like with the AR tutorial where I can integrate my own detection)
