Add Ios support

[Wavesonics]

I added the iOS KMP targets here for issue #1

I had to compile the new libs for the cinterop, so I grabbed the latest .c from here:
https://github.com/kuba--/zip

Which also required me to grab their latest headers. Should be fine? But maybe it'd be worth recompiling all of the platforms from the latest kuba/zip?

On second thought, it's a simple .c file, you could include it in the repository, and gradle or CI could build the artifats as part of this project, idk. Just spitballing.

Okay, I added the zip.c file, so any recompiling of artifacts is sure to use the exact same version

Hi @Wavesonics, thank you for the PR!

What were your build steps of kuba zip for the different targets? Do they differ from the ones described in #2 (comment)?

I know that kzip currently does not provideany tests, which is still something that needs to be added. How did you test whether the new targets behave as expected?

Yeah, integration of the kuba zip build into the gradle setup is definitley something that is needed.
Then we can use GitHubs macos runners and do not have to rely on contributors with macs.

Check out #5, I brought over the test suite from Kuba Zip to verify the iOS implementation

will have to dig through my stuff from yesterday, but it probably won't be today
