Add a pyjsontool which uses the json format to download files.

Also add a message when a file is invalid.

I'd prefer not to create fractional support here - given the new binary will be multiplatform.

[jwhite66]

Sure, I understand your reasoning and this is your call. I'll just note that I have a strong preference for a CLI tool, and a simple one in Python is very compelling to me. What's important is that we all rally behind a single data file.

Can you rebase this into a new folder to consolidate the Python stuff?

[jwhite66]

I've rebased this branch. It sounds like you'd like to move the python scripts into a separate directory. My inclination would be to create two new subdirectories; an archive and a scripts directory. I would move all of the .CSV files into the archive, along with the pyusbtool.py script; I would rename the pyjsontool.py back to pyusbtool.py and put it in the scripts folder, perhaps with a README. Would you like me to do that?

[JamieSinn]

I'll move the old csv files after the 2025 season - as the previous v1 tool will break by doing that and I still want to maintain compat for at least this year - as it looks for the specific root folder CSV - but otherwise that would be great!
