Support custom labels and badge styles. Add License. Upgrade and Remove unused dependencies.

Live Demo

Deployed on render.com free tier.

Proposed Changes

• Support custom labels and badge styles, similar to what shields.io offers.
  • Made possible by replacing badge crate with rsbadges crate (BSD 3-Clause License).
  • The new crate supports badge logos, but I'd consider it out of scope for now.
• Add Apache and MIT Licenses. Addresses Add libre license #103
• Add some files to gitignore based on standard Rust gitignore template.
• Upgrade and Remove unused dependencies.
  • GitHub actions and earthly versions bumped to latest
  • Rust version upgraded to 2021
  • Cargo dependencies bumped.
  • Unused Cargo dependencies removed to reduce compilation time (sidenote: long compiliation time was causing builds to fail on render.com free tier, this may not be an issue on other hosting platforms)

Known issues

Getting 403 errors with ghcr.io

In deploy.yml, sometimes the default ${{ secrets.GITHUB_TOKEN }} may not work well with ghcr.io.

A workaround would be to create and use a GitHub Personal Access Token with write:packages access enabled, no expiry date, and add it to this repository (e.g. ${{ secrets.PERSONAL_ACCESS_TOKEN }}).
