Simple Esp32 async web server

Libraries/reference:
https://github.com/me-no-dev/ESPAsyncWebServer

Basics:
I'm using this code to turn a relay module on and then off after 1 second.
It creates a simple web server where I can use the / route to check if its alive and the /actions route to trigger my relay module.
I also included a simple access token check for basic security.

Here's an example of the two routes we get:
http://192.168.0.10/
http://192.168.0.10/actions?code=123456

Before using this code:

• Install the necessary libraries
• Define the pins of your choice
• Check if you need a positive or negative signal to turn on the relay module
• Change the Wifi settings to match your router
• Choose a good access_token to use later when accessing the web server
• Choose for how long you want the relay to stay on when triggered
