inline-c-objc package for Objective-C support (fixes #142)

Let me know if anything should be done differently.

Note that I believe this will mostly be used to interface with macOS/iOS APIs, so I haven't tried testing it platforms other than macOS.

Hi, inline-c has a flag to parse c++. If this test does not work, you should update the parser of inline-c. https://github.com/fpco/inline-c/blob/master/inline-c/src/Language/C/Types/Parse.hs#L126

If this test does not work

Which test?

Thanks, I'll try to take a look this weekend.

Thanks!

~I have no real rush as for my problem I ended up using C APIs only but it will hopefully be useful for others :)~

Edit: Lamdu ended up using this :)
