Update extractor script

[queengooborg]

This PR updates the new traceKeyExtractor.py script to perform the following:

• Removes the need to modify the script file to specify the installation path of Proxmark3, both by leveraging Homebrew directly to find the install path (avoiding cross-platform and cross-architecture issues) and adding the ability to use an environment variable to specify the installation directory.
• Adds a .gitignore to ignore any dictionary files generated by the script.
• Updates the logging output to include step-by-step instructions on the complete trace process

Could be that we're running different python versions

That would make a lot of sense as to why you're getting lots of errors that I'm not -- what version of Python are you running if I may ask? I'm running Python 3.12.3 personally!

Edit: figured out the real reason for the errors and got it fixed accordingly!
