Feature: Scheduled/periodic runs about image-actions

[tunetheweb]

It will attempt to recompress it, but if it doesn't find significant savings then it will ignore it. This is also what happens if you upload an already optimised image.

I run this ever Sunday in my repo, and though the first few runs spotted a few uncompressed image after that it settled and now basically never alerts unless I really add an uncompressed image to the repo: https://github.com/HTTPArchive/almanac.httparchive.org/actions/workflows/compress-images.yml

When #54 is merged then this can be done with an action something like this:

name: Compress images every morning at 8am, opening PRs if necessary
on:
  schedule:
    # * is a special character in YAML so you have to quote this string
    - cron:  '* 8 * * *'
jobs:
  build:
    name: calibreapp/image-actions
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repo
        uses: actions/checkout@master

      - name: Compress Images
        id: calibre
        uses: calibreapp/image-actions@master
        with:
          githubToken: ${{ secrets.GITHUB_TOKEN }}
          compressOnly: true

      - name: Create New Pull Request
        uses: peter-evans/create-pull-request@master
        with:
          title: Compressed Images
          branch-suffix: timestamp
          commit-message: Compressed Images
          body: ${{ steps.calibre.outputs.markdown }}

@tunetheweb @benschwarz
I have a question - will Github Image Action compress an already-compressed image? Let's say we have scheduled Image action to run every Sunday at 11:00 pm, so every time will it compress an image that is already optimized?

Thanks !
