Add save and restore actions

[mattlewis92]

Changes

Adds save and restore sub-actions to match the official actions cache behaviour and make this action a true drop in replacement for the official github cache action.

Usage is fairly straight forward, to save to the cache only (note the /save at the end of the uses key):

      - uses: tespkg/actions-cache/save@v1
        with:
          accessKey: "Q3AM3UQ867SPQQA43P2F" # required
          secretKey: "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG" # required
          bucket: actions-cache # required
          # actions/cache compatible properties: https://github.com/actions/cache
          key: ${{ runner.os }}-yarn-${{ hashFiles('**/yarn.lock') }}
          path: |
            node_modules

To restore only (note the /restore at the end of the uses key)::

      - uses: tespkg/actions-cache/restore@v1
        with:
          accessKey: "Q3AM3UQ867SPQQA43P2F" # required
          secretKey: "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG" # required
          bucket: actions-cache # required
          # actions/cache compatible properties: https://github.com/actions/cache
          key: ${{ runner.os }}-yarn-${{ hashFiles('**/yarn.lock') }}
          path: |
            node_modules

Fix Issues

Closes #38

Looks good so far, can you add a test workflow to test just the saveOnly part? You can start by copying this file: https://github.com/tespkg/actions-cache/blob/main/.github/workflows/test.yml to a new file and modify the bits needed.

Sure thing! Added here a4b7cac + here 18d4ac5

I'm not sure this tests the new functionality. Can you elaborate how does this test the restore-only?

In my previous comment, I meant that you should make a new file and use your pattern of "save" and "restore" actions.

[mattlewis92]

Note how it uses the new sub-action that restores only via the uses: ./restore/ here:

https://github.com/mattlewis92/actions-cache/blob/18d4ac58ee9683f4c7ea366fee85bcc0fa578240/.github/workflows/test.yml#L184

They could be put into a different workflow, but it seemed redundant to me as it also functions just fine in this one. I can move it into a separate workflow if you'd prefer though

The tests is setup so that it logs the machine ID it runs on and restores on the same machine. I know, it can be so much better, but it works so far. So a separate file will probably put it on a different machine. Hence tests the actual thing. If put in the same file it'll pick up from the previous step.

After written all these, I realised you do distinguish using the key. so all good for me.
