Validate exported CB lessons and pass them to corresponding Lessons in Code Studio

[davidsbailey]

FInishes PLAT-498. Builds on the existing script for importing CB data as follows:

• validates chapter data, and wraps any lessons owned directly by the unit in a single chapter
• matches and validates CB lessons with code studio lessons by comparing relative position, lockable state, lesson name, and the stage name from code studio pull-through if present
• calls new placeholder Level#update_from_curriculum_builder method for each code studio Level with corresponding CB data

Sample verbose output:

Testing story

Lesson name warnings look mostly harmless:

My unconfirmed suspicion as that mismatches are limited to express, pre-express and CSP because those courses do not actively use code studio pull-through, whereas Courses A-F and CSD do actively use it.

Future work

Aside from other work tracked in the same Jira epic, we may want to add another option to the command line script which allows running against a specific lesson or list of lessons, so that the script can be used to test out import one lesson at a time.

I'm not super familiar with all these relationships still, but looks good to me. I say ship it!

Hey Dave - I looks like CSP 2020 uses chapters on the LB side. https://levelbuilder-studio.code.org/s/csd1-2020

Hey Dani, that looks like a link to CSD, but your point is still valid -- CSP 2020 does use lesson groups on the LB side. I am using "chapter" to refer to data coming in from CB, and what I am trying to say here is that CSP 20 does not use Chapters on CB.

It would probably help if I clarified when I am talking about CB data without relying on the assumption that "chapter" means CB. I will update this in the next PR.

Sounds good. I just wanted to check. (Sorry about the wrong link lol)
