jupyter V2.1 with backwards compatible changes

[zilto]

Reimplementation of #846 with backwards compatible changes with V1.

Compared to V2:

• support module_name as positional or named arg (-m/--module_name)
• support -c/--config
• support -h/--help
• ignores -r/--rebuild-drivers
• ignores -v/--verbose
• richer support for -c/--config
• alias %%insert_module to %%module_to_cell
• creates a temporary file for the temporary modules to play nicely with Hamilton UI

Currently ignores the %%incr_cell_to_module. We have to consider what it means to deduplicate these 100+ lines of logic. If this feature truly adds value, it should be an argument instead of a separate magic. I propose -a/--append INDEX. This means the magic would now require to be stateful though opening opportunities for more bugs.

How I tested this

The notebook tutorial.ipynb covers all implemented functionalities, so it's a good test for intended behavior.

TODO

• Manually test all notebooks using %%cell_to_module
• Reimplement the 2 notebooks currently using %%incr_cell_to_module
• Update documentation

looks good, but undelete %incr_cell_to_module

Looks good. I assume you've tested it, e.g. %incr_cell_to_module still works? :)

Cool - I'd squash merge this PR when it's ready.
