Add Token Auras

[SeamusFinlayson]

Make sure that your submission has the following:

• A link to the raw github markdown file with a YAML front matter definition containing:
  • The title of your extension
  • A description of your extension
  • The author
  • A hero image
  • An icon
  • Tags (these will help with your extension's discoverability)
  • A link to your extensions manifest

Please, go through these steps before you submit a PR.

• You have done your changes in a separate branch.

• You have a descriptive commit message with a short title (first line).

• You have only one commit (if not, squash them into one commit).

• Your pull request MUST target the main branch on this repository.

• Your pull request puts your extensions details as the last entry in the extensions.json file

Validation script and image URLs check out fine. Extension functionality and API usage not checked.

Just a couple of thing:

• Could you make the homepage_url in the manifest go to the extension github instead?
• The aura doesn't take image alignment into account, the aura isn't centred if the image alignment isn't in the top left

• Oops, forgot to add the repo
• Alignment should now be accounted for, as well as rotation and scale

Looks good!

I think you could make this a little more mobile-friendly by changing the UI to take a little more horizontal space rather than vertical but that's just general feedback :)
