Fix or update example code that makes assumptions about non-blocking run_sketch()

From @villares on mastodon:

Cheers @hx2A, this example assumes you are in an environment where py5.run_sketch() is non-blocking by default (the Jupyter Notebook environment if remember correctly). Maybe you should make and example where an event like a a key pressed triggers the stats printing?

There are probably other examples that make the same assumption.

There are probably other examples that make the same assumption.

This is in 14 other places. For some of them, there isn't a way to re-write the examples to work if py5.run_sketch() is blocking. For those, I will change the example to use py5.run_sketch(block=False), which doesn't make any assumptions.

This is now fixed.

The example for py5.print_line_profiler_stats() now uses the key_pressed() event.

Here are some examples of examples that now use py5.run_sketch(block=False) :
