A roughdraft for moving pycares to cython. hence the underscore

## Why Rewrite pycares?

- While pycares runs aiodns which optionally runs aiohttp there's some pretty alarming and unsafe code that hangs while during shutdown 

- the library has had [recent vulnerablilities](https://github.com/saghul/pycares/security/advisories/GHSA-5qpg-rh4j-qp35). 

- cython is faster than cffi and can be straight up compiled statically rather than being ran dynamically

- rewriting the code in cython means you could use pycares in cython as well which only means more benefits in speed.

- rewriting the way the handles work in uvloop fashion might be safer as well as making

  the channels shut them down instead of having another thread do it.

- pycares's shutdown mechanisms are not threadsafe and users using tools such as [aiothreading](https://github.com/Vizonex/aiothreading) may experience unwanted performance degredations.
