feat: get ResultPoints of code result

[tomfong]

This PR just provides idea of what I want to implement...

I would like to get points of the result when scanning. I know where I should put new codes to but I'm not familiar with ``JSObject``` in both Java and Swift. So the PR is obviously not finished and tested.

So @thegnuu, could you please help and guide me? I would like to know how to serialize Swift's Struct[] and Java's Class[] to JSObject's Object properly.

Thank you very much.

@tomfong as pointed out in your issue I will have a look at it in the upcoming days! Please give me some time :)

Thanks!

#140 It might be possible that this would be useful for the same reason

I should be able to add this with the upcoming ml-kit solution, unfortunately, I will not be able to merch this PR since the complete code base changed.

Thank you anyway for your work!
