When sending raw data, the library sets the same mtu size for every service type

[NicoleYarroch]

Bug Report

When sending raw data, the library sets the same mtu size for every service type. However, since we get and save the mtu size for video and audio services, we should retrieve the correct mtu size for the service type.

Reproduction Steps

In the SDLProtocol class, thesdl_sendRawData:onService:encryption: method retrieves the mtuSizeForServiceType using the SDLServiceTypeRPC. However we send video and audio data using this same method. Instead of using SDLServiceTypeRPC to get the mtu size, we should use the passed service.

Observed Behavior

The production head units that I have tested with use the same mtu size for RPC, video, and audio services, however this may not aways be the case in the future or on other production head units.
