Adding more BP topic types

[phuicy]

I have implemented more of the BP features.

I will do more. But this is what I need for the moment.

Hi @phuicy
Thank you very much for the BP. Adding types is always highly appreciated.
Based on the title of your PR, i wondered about the changes in the ROSIntegrationGameInstance and the TCPConnection core functionality.
What is the rationale behind these changes?

/edit: Ah, i see now. This is basically the same changes as in #181 , right ?

[phuicy]

Sorry yes, commit: 7798308 was meant to be cherry picked out for #181.

I will remove that from this branch now.

@Sanic Resolved.

@phuicy Great! Thank you very much.

@phuicy How did you get this to compile? I'm using UE4.26 and I get a compile error saying "Type 'double' is not supported by blueprint." from the void OnFloat64Message(const double& Data) function you added in RI/Topic.h. I'm guessing you're using UE5?

I've tried putting the UFUNCTION inside a preprocessor directive that checks to see if we are using UE5, but UE does not allow UFUNCTIONS to be placed inside preprocessor directives. I'm thinking we need to remove the OnFloat64Message function.
