rhcp011235/MTK_KEY_CONVERTER_TOOL ? reverse-engineered prompt

Build me a small Python tool that takes a CM2 or Pandora log and turns it into a keys.json file for Oxygen.

I want it to be simple to use, like I can drop in a log file, run the tool, and get the converted keys file out the other side without having to do anything complicated. If there are a few common log formats or messy lines, please make it handle them as well as it can and ignore anything it does not need.

Keep the app focused on just this one job, and make the output clean and ready to use. If you need to check current format details online to make sure the conversion is correct, go ahead. Also include a basic way to run it from the command line and a couple of clear examples so I can see how to use it.
