Sanic instalation on Windows

[lucasvfventura]

Hi,

In order to install Sanic on Windows I went over the instructions to install it without uvloop and ujson, commands:
set SANIC_NO_UVLOOP=true
set SANIC_NO_UJSON=true
pip install sanic

I got the follow output, with the exception of {User} was my user:

RuntimeError: uvloop does not support Windows at the moment

Although when I clone the project and do the following commands, it is successfully installed:
set SANIC_NO_UVLOOP=true
set SANIC_NO_UJSON=true
pip install .

It might make it a little more friendly to use sanic to tweak the setup.py to check the system it's installing on:

# setup.py
...
is_windows = sys.platform.startswith("win")
if strtobool(os.environ.get("SANIC_NO_UJSON", "no")) or is_windows:
    print("Installing without uJSON")
    requirements.remove(ujson)

# 'nt' means windows OS
if strtobool(os.environ.get("SANIC_NO_UVLOOP", "no")) or is_windows:
    print("Installing without uvLoop")
    requirements.remove(uvloop)
...

Or along the lines of #916 maybe make ujson and uvloop extras_require so you opt-in on pip install with pipenv install sanic[ujson,uvloop].

@jamesstidard we merged #1117 in feb which should cover this, sanic just hasn't cut a pypi release in a while

With the 0.8.x release, this should be resolved.
