Add OBj-C implemenetation?

[Motti-Shneor]

Hi, I downloaded your repo, and was unable to use it as is, because our MacOS project must be all Obj-C. So...

After fixing the project and upgrading it to swift 5 so it runs and so on -

I back ported the framework into ObjC, initially tag-for-tag, but then I couldn't resist and made it a little more concise, "C"-ish and highly optimized. I make this a new target in the same project, and made sure the Swift sample app uses the OBj-C framework with no issues, and it works the same.

Are you interested in this code? Would you want to introduce this addition to the repo?

Sorry I'm making this an "Issue" because I can't find any other way to communicate with the developer.

Well. no reply here - so I just attach a zip of the modified project, for whoever wants it. Sorry I don't know how to "Branch" and create a pull-request or however it's done here.
