Add fibonacci sequence generation as example

[wusatosi]

Adds an example that shows generating a fibonacci sequence as a example.

Packed a very partial size fix to let the example compile.

Overall looks good, just some minor comments.

Regarding the examples in general, are we mandating that they build with all the supported C++ standards that inplace_vector supports?

Thanks for the review, we will eventually add more constexpr examples, e.g. fib with cache for i < 100 computed at compile time or smt. We will need to selectively enable it as it would not be supported on C++ 17 (unless we figure out a way to support constexpr on 17).

Example of this being done in exemplar: bemanproject/exemplar#56

Ok sounds good, thanks for the link. I have missed the last few sync calls so I'm a bit behind. I only asked because it would be nice to use std::print() instead of iostreams in the example(s). But that's just being nitpicky IMO. I don't have an issue landing this PR as is.

[use std::print instead of iostream]

Don't forget we are still on C++20/17 for this library :P

Thanks for the review, merging...
