Use Repo as Stub Source

[BradenM]

Setup this Git repository to work as a Stub Source (primarily for micropy-cli).

Basic Idea:

• Automate the creation of a "package branch" for each stub package. This branch's root is created from the git tree object on the master branch. (ex. origin/master/micropython-official/v1.11/esp32 == origin/pkg/esp32-micropython-1.11

• Use Githubs integration of git archive to download [stub_pkg].tar.gz files from this repo.

• Automate upkeep of a repo.json file in the project root which has the following basic schema:

{
  "name": "repo-code-name",
  "location": "https://url.com/repo.json",
  "path": "https://cdn.url.com/repo/branch",
  "packages": [
    {
      "name": "esp32-micropython-1.11",
      "path": "pkg/esp32-micropython-1.11.tar.gz",
      "type": "device",
      "version": "0.0.0"
    }
  ]
}

This has been completed by automatically creating stub specific branches (filtered) which can be downloaded from via Githubs archive functionality.

This alongside a source.json file at the repo's root which is used to reference the branches from a client.
