Generate from templates

[irsdkv]

At this time we can go forward and implement generation from templates.
Hopefully I will return from my vacation in middle of January and will start that 😄
Additional info: #6

About API stabilization:
I think we can start as is and try new in process of templates generation implementation.
@julianoes @JonasVautherin if you will have any questions and suggestions related for current API (in develop branch) or any other - please create new issues or requests and I will try to answer as fast as possible

[danieleades]

out of curiosity, what is the benefit from this approach? what are you trying to achieve using the templates?

I have no idea now, it was too late 😅

@danieleades The templates are used by protoc-gen-mavsdk to generate the code from the definitions in https://github.com/mavlink/mavsdk-proto.

The idea is that once you have written the templates, then all the changes coming in the core C++ implementation can propagate automatically to the language bindings. That's how we manage to keep MAVSDK-Java, MAVSDK-Python, MAVSDK-Swift up-to-date: most of the work is done in MAVSDK-C++.

Also note that historically we started by using gRPC to talk between MAVSDK-* and MAVSDK-C++, but it could use FFIs. I think it would actually be our preferred approach today.
