Delonghi Penguino PAC W120HP ir support

[grob6000]

What does this implement/fix?

Add support for a slightly odd delonghi infrared protocol. Used the daikin module as a guide.
I've done this mostly just for myself; so I haven't got around to checking whether this is the current best practice way of adding support for a device, or documenting properly; if this has any support for inclusion, after any modifications I'm happy to fix the docs etc. then.

LGTM, thanks!

Please additionally:

1. Add a really simple entry in the tests/ folder (it's just there to test if the codegen produces compilable output)
