Add Server functionality

[mscosti]

This is still a work in progress, but opening it up for early feedback and suggestions.

• Adds Server creation methods to esp32spi.py
  • Instantiates a server on the esp32 on the specified port and a specified socket that was previously requested
• Adds a new example file that creates an access point from secrets.py and then a server on port 80
  • Logs when a device connects or disconnects from the access point
  • When a device hits <serverIP>:80 (like in their browser), send back simple HTML page that has a couple of anchor tags on it

Todo

• rebase with master once Add Access point mode #57 is merged
• Make the example code more polished and more fun.
• Create a new helper class to manage server creation and management.
• Thinking we could even go so far as to implement simple request handling. Something like:

     Server.on("<HttpMethod>", "</routeString>", callbackFn)
     ... 
     def callbackFn(data, socketToWriteTo):
  

  • This Might be confusing since the run loop would need to be handled outside code.py?
  • At the very least could have a method to check if a certain route is triggered?
  • Could instead have a more feature rich web server lib (like flask) live outside of this to keep it focused.
• More cleanup
• More testing
• Fix linting errors + get green build

@mscosti Are you going to open a new PR for this?
