Added support for RC5 extended

Browse Source

Excerpt from PR:
```
Hi,

I added support for 'RC5 extended' in order to make this project:
https://www.instructables.com/id/Remote-Control-for-Lava-mMotion-Swing-Mounting-Bra/

The modification is working nicely in this single application. It has
not been tested elsewhere.

(I am new to Git and this is my first pull request ever. So please
excuse me if I have messed something up)

Kind regards,
Lars
