Added support for Gorenje cooker hood IR protocol (#1888)

Closes: #1887
```
// Supports:
//   Brand: Gorenje,  Model: DKF 2600 MWT Cooker Hood
```
See [here](https://github.com/mbronk/IRremoteESP8266/blob/416798dd5ae2ced324dade0972111bc79a7eb504/test/ir_Gorenje_test.cpp#L120) for raw data examples.

_Cheers!
