Create Initial Package

[kevinfodness]

• Create initial package with ability to run bulk tasks and maintain a cursor to keep track of position in case it needs to get stopped and started
• Add common files for packages, like GitHub Actions to run tests, phpcs, phpunit, .editorconfig, README, contributing guidelines, etc.
