Raspberry now supported by rcswitch library / This library is outdated

[technyon]

The Raspberry is now supported by the original rcswitch library:

This code is outdated, I'd recommend using the rcswitch library instead. It's easier to add new protocols (defined in array instead of several if-then-else statements) there, and the timing seems to be better (my rc outlets switch more reliably).

If possible, please add a note in the readme to redirect people to rcswitch.
