Should we be removing the C example device?

[burgholzer]

At the moment, we provide two example devices (C and C++).
While this is a nice exercise, it

• increases the workload when changes to QDMI are proposed,
• increases the chance of both examples getting out of sync, creating a source of inconsistency, and
• promotes device implementations in pure C, which I would argue are not really convenient.

I'd personally favor simply removing the C example device.

@ystade opinions?

I think one motivation was that we also see how the interface looks and feels from the C point of view. However, since I do not see any way of not detecting an incompatibility by only implementing a C++ device that would occur when one would implement the same in C (since the interface is C and as long as we do not abuse the interface by performing some strange pointer casts in the C++ device), I am happy to drop the C device. I assume that no one is using it anyway.

I agree. I'll tackle this once #160 is merged.
