Injecting configuration when starting programattically

[davetapley]

I'm starting NiceGUI programmatically (see also #4613).

My current approach to pass configuration using the storage API, thus:

from nicegui import ui
import gui.main  # noqa: F401 

class GuiProcess(SpawnContext.Process):
    def __init__(self, stuff):
        self.stuff = stuff

    def run(self):
        super().run()
        app.storage.general['stuff'] = self.stuff
        ui.run(reload=False, require_main_process=False) # see https://github.com/zauberzeug/nicegui/pull/4613

Where gui.main defines my @page functions and loads from storage:

@ui.page('/')
async def root():
    stuff = app.storage.general['stuff']
    ui.label(stuff)

And start thus:

stuff = "Hello, world"
gui = GuiProcess(stuff)
gui.start()

It works just fine, but I wanted to put it out there in case anyone has an other ideas.
