Asyncio support

[edgeinfinity1]

Quite a rough one, using httpx instead of requests.
Comes together with a simple example.

Is this a breaking change or is this compatible with all older code too?

This breaks the original searching function.
For a fully compatible version, I can separate the async part into a new function. Or you can change it in this PR too, it's simple.

Progress: Now added compatibility to sync search function.
Async searching now named asearch.
Async searching supports socks5.

Sorry for the late response! Would you mind putting it in a separate file just to make the code a little cleaner?

I'd like to but the main structure was set in the init file. It should be a separate file itself so I can make a symmetric one.
Could you sort that part out first?

Sorry about the long delay! Couldn't you add from .<filename> import asearch into __init__.py and separate it out like that? What do you mean by the main structure?

Optimized as requested.
