Update CI to support ARM build

[WhiteSte]

According to #61 (comment) I've tried to modify the CI in order to build the natives also for mac os arm64 architecture. The service flyci-macos-large-latest-m1 should be free on public repos for 500minutes/month, that should be quite enough as a temporary solution.

I'm not an expert of github actions, how can i test the pipeline if it works?

Thanks for this PR!

We also need modifying the publish section: https://github.com/PDAL/java/blob/main/.github/workflows/ci.yml#L132-L135

'upload' uploads built artifacts and then we 'download' them to pack into the result package.

I'm not really practise, should we add

 - uses: actions/download-artifact@v3
        with:
          name: macos-ARM
          path: native/target/native/arm64-darwin/bin

Something like that after L 135?

I think the best way to test is configuring and testing CI in your fork. Sadly there is not really good way to do it.

Thanks for making a PR!

sounds like the new m1 runner is also building x86 arch and the old mac os one is building also arm arch . I will revise that

[pomadchin]

Interesting, these runners were not even allocated 🤔

[WhiteSte]

umh maybe @kgantchev can give us some clarifications

[kgantchev]

Thanks, I'll look over the thread in a bit and I'll get back to you with more info ASAP.

BTW, what do you mean here?

Got it. We had an issue yesterday which we resolved. I'll check with our team to see if you might have been affected. My apologies if you experienced an interruption!

@WhiteSte we don't see an app installation for this GitHub account. Please make sure that you have installed the FlyCI GitHub app on the PDAL account.

@WhiteSte you can also fork the repo, install the FlyCI app, and run the actions in your account to validate that everything is working properly before making the contribution here (I assume the maintainers will be the happiest with that approach).
