Complement RAF-Avia Flightplan

[Drebing]

Hello everyone.

I installed the RAF-Avia flight plan and found that the registrations YL-RAG and YL-RAE shouldn't be available.
I have already painted these. Available at https://ai-flightpaints.weebly.com/raf-avia.html.
You are welcome to include them in the AIM.

Greetings,
Drebing
