Adapt gevent to improve client operation about pxblat

[cauliyang]

current method

from pxblat import Client, Server


with Server() as server:
    server.wait_for_ready()
    client("atcg")

Future

from pxblat import Client, Server


with Server() as server:
    server.wait_for_ready()
    client(["atcg", "CTag"])

using gevent as backend for multiple querys, and make multiple querys as default support.

from pxblat import Client, Server


with Server() as server:
    server.wait_for_ready()
    client(["atcg"])

Ideas

• support mixed usage of lower and upper case for sequences i.e. "atcg", "aTcg"
