Update Package Names and Add Legal Info

[brhook-aws]

Description

Updated all of the package names to be the agreed upon names. Likewise, updated all references in code that pointed to old folder directory or was a customer visible label. Also, updated the "SumerianToolbar" class for each package to better reflect new name.

Additionally, as part of this change, I've added some legal safeguards to the code:

• Added NOTICE and LICENSE file to each sub-package
• Updated header of all files to include appropriate license information
• Updated package.json for each package to better represent author, description, and repo information

Note

This change is built on top of this PR, as I am unable to build successfully without. That change should be committed first before this one goes through.
