Example code in ReadMe won't run.

[Julian-O]

The Readme contains some example code.

One example demonstrates that servers are also clients:

• It imports time.sleep() but never uses it. Meanwhile, it uses time.time() without importing it.
• It has a variable called cont which is never defined.
• It does a busy wait, which is not demonstrating a good way to use the API.
• It keeps appending True to a list (Why not just count?), but never popping it.
• ping takes parameters, but it isn't clear what they represent.
• pong doesn't use the *parameter. Rename it _.

One example demonstrates that async servers.

• It imports OSCThreadServer but uses OSCAsyncServer

One example demonstrates how Unicode is used.

• Uses OSCThreadServer without importing.
• Uses send_message() without the expected osc. prefix.
