Various improvements

[KTibow]

Fixing hacs.json and improving README. Also: I recently announced ha-blueprint:

• With formatting (black + isort for python, prettier for js)
  • It’ll go ahead and pull it, format it, and amend the changes to the last commit.
• With lint
  • JS: Run ESLint to catch syntax errors
  • Python: It runs Hassfest (to catch invalid integrations), HACS (to catch invalid HACS integrations), and flake8 (to catch invalid python).

https://community.home-assistant.io/t/made-a-custom-integration-or-card-ive-created-an-all-in-one-github-action-for-you/235041 This makes it so it auto-checks for HACS, hassfest, and flake8 so you won't have to worry about it being invalid.
