Updated Arduino Examples file format

[antronyx]

Hello devs!
Examples from this libraries are still in .pde format, deprecated from Arduino far more than 10 years ago.

New editors (I tested 2.0.3) can't even open those examples, so I think it's time to update.

Since .pde files are quite obsolete now, would it be possible to update the examples format from .pde to .ino and make a new tag of the library?

Thanks a lot!
