Windows does not support os.fork

[SystemPanic]

Describe the bug
Windows does not support os.fork

Starting a socketify ASGI, for example falcon, raises AttributeError: module 'os' has no attribute 'fork'

To Reproduce
Steps to reproduce the behavior:

1. Create a file called falcon_test.py with the following code:

import falcon
import falcon.asgi
from socketify import ASGI

class Test:
    async def on_get(self, req, resp):
        """Handles GET requests"""
        resp.status = falcon.HTTP_200  # This is the default status
        resp.content_type = falcon.MEDIA_TEXT  # Default is JSON, so override
        resp.text = (
            '\nTwo things awe me most, the starry sky '
            'above me and the moral law within me.\n'
            '\n'
            '    ~ Immanuel Kant\n\n'
        )

app = falcon.asgi.App()
test = Test()
app.add_route('/', test)

if __name__ == "__main__":
    ASGI(app).listen(5000, lambda config: print(f"Listening on port http://localhost:{config.port} now\n")).run(workers=8)

3. Call python falcon_test.py

Expected behavior
ASGI server running on Windows.

For now, we depend on os.fork so windows is not supported yet, but will add this feature in windows in the future for sure multiprocessing should do the trick
