Improve event processing performance

[picklelo]

• Reorder if statements in format_state to handle most common vars first (this provided a big speedup)
• Use super().__getattribute__ in functions in the critical path of event processing. It's ugly but it's faster.
• Add onopen for web socket to hydrate the page on initial load.

Test code:

# Perf testing...
import asyncio

from pynetree.pynetree import app
from pynecone.event import Event
from pynecone.app import process
token = '0'

async def do_loop():
    event = Event(token=token, name="counter_example_state.increment")
    update = await process(app, event)
    print(update)

async def main():
    for i in range(10000):
        print("loop", i)
        await do_loop()
    
asyncio.run(main())

Remove the print line in performance benchmark, it will slow this code down.

Remove the print line in performance benchmark, it will slow this code down.

It does slow the runtime, but I'm only visualizing inside the process function so the results should still be valid.

Will we eventually change this so its on socket per app

[picklelo]

I'm not sure tbh, we will need to investigate this.

Nice the reordering speed up
