`click` Vs. `argparser`

[gvee-uk]

The current CLI implementation is using argparser.

However the TDS cookie-cutter project prefers click.

We should at least evaluate which one would be better suited for this application!

Considerations:

• I'm not the biggest fan of the way the replacement-tokens is implemented (JSON on the CLI is less-than-fun). If click has a better way (I believe it allows for multiple/nargs in a nicer way) then it should be considered
• Testability
• Packaged size (we use pyinstaller to bundle up the Python libraries, so how does the bundling compare with each library?
