Refactor the analytics command

[pvdz]

This refactors the analytics command:

• Moves it into its own folder
• Separates the CLI side of things from the actual command
• Not having index.ts makes debugging and development easier (no more "guess the index.ts" roulette)
  • I'm torn between file naming. run-foo makes sense because it's a verb whereas foo-command makes sense because it's a noun. So now neither the type nor the command will be consistently grouped together... Perhaps it should be cmd-foo instead and the actual functions a name that matches the main function?
• Cleans up imports that were deep-importing rather than from the top
• Eliminates a bunch of any's
• Functions explicitly typed
• Flags explicitly typed
• The command file has its parameters and details clearly at the top
• The command file deals with CLI flag handling and what not
• The run file deals with running the actual thing
• Did not change semantics of the actual thing (or cli), may want to look into that later
• The CliCommandConfig type is a bit of a trial. May refine that as more commands are refactored this way.
• (Probably true for the structure on a whole)
