dev: consistency checker for npm packages

[haraldschilly]

Description

just an idea, this could help us getting insight/warnings about version inconsistencies (e.g. as part of CI testing)

the only change that touches anything is calling this at the start of webpack-watch, to give us some feedback. Later, once this is down to zero inconsistencies, we can add it to travis CI to inform us about introducing new ones.

Testing Steps

Relevant Issues

Checklist:

• No debugging console.log messages.
• All new code is actually used.
• Non-obvious code has some sort of comments.

Front end:

• Restart at least one project and check its ~/.smc/local_hub/local_hub.log
• Completely restart Webpack with ./w in /src
• Completely restart the hub by killing and restarting ./start_hub.py in /src/dev/project
• Screenshots if relevant.

Nice use of mypy typing... when/how would the typing get checked ?

well, those are the usual type annotations. you can use mypy, but also pycharm, vscode (pyright?) and several others to check. the canonical one is probably mypy. run it via mypy [filename].py.
