Add opticks cli

[dale-french]

Description

This PR does the following:

• Migrates the project into a Yarn Workspaces monorepo and introduces two packages, namely:
  • lib: The existing opticks library
  • cli: A new CLI called opticks-cli which handles automated cleanup of toggle code
• Removes JsCodeShift scripts from opticks

CLI

This is a first version of the CLI so does not come with all the bells and whistles (YET!). At the moment the CLI takes care of running JsCodeShift codemods in a way that is more user friendly than the existing scripts. In the future, this CLI will also be able to take care of removing unused files and dependencies used on the cleaned up side of the experiment using Knip.

At the moment, the CLI looks like this:

Without options specified

With options specified

Next steps

As this is a first version, I would like to test this in the real-world before making any additional improvements. Upcoming improvements would look something like this:

• Publish both packages using changesets - currently only opticks is published automatically
• Add Knip to clean up unused files and dependencies
• Update documentation for opticks and opticks-cli

Technically opticks supports a, b, c, d, etc https://github.com/viodotcom/opticks/blob/master/src/core/toggle.ts#L11

Should we allow it here too?

[dale-french]

I think for ease in the beginning we keep it as is and expand if we think its necessary (I think there has only been 1 MVT since I joined?) - we can always use the full command if needed:

opticks-cli clean --id=ab-test-123 --winner=c

OK fair enough, though I think we should design it to be flexible, optimizing for the most used case is fine here.

Thanks for making the clean up process a lot nicer, @dale-french 🎉
