WIP: Native curl

[Conni2461]

Close #62

Two passing tests. The other stuff is not implemented 🤣

A lot of stuff is missing or hard coded. I just wanted to make sure that its actually possible that i can do a get with ffi and libcurl.

Now:

• Implement enums as lua tables
• Implement missing easy interface functions
• Handle headers
• Post/Put/Patch/Delete/Depug
• Additional extension for native using curl_multi and whatever other cool stuff can be found in libcurl
• Provide async interface for simple stuff with uv.new_work
• Make sure we have the same interface as curl.job or more.
• Remove scratch files
• Implement fallback swapping
• Fix CI. Probably missing libcurl. So we want to run test on both interfaces. Job and native. Not on the public interface / swapping interface
• Missing stuff
• Still missing stuff 😆 for sure
• Maybe Profit

I actually think this is bad and is just reinventing the wheel. Also i don't have the time to do it 😆
