Automatically set `Rightarrow` #2

At the moment, nfold=1 is not permitted. This means nfold should only be used when Rightarrow is used (and, indeed, there are graphical issues if it is not used). Therefore, it would make sense for the nfold parameter to automatically set this option.

Thank you for the suggestion. tikz-nfold can be used on arbitrary TikZ paths and is thus not restricted to tikz-cd, while Rightarrow is a tikz-cd feature. What would be your expected behaviour here? One idea that comes to my mind is for nfold to set Rightarrow depending on whether we are in a tikzcd environment (if that is possible).

Ah, I had overlooked that, it's a good point. I think that overloading the behaviour in a tikz-cd context specifically would be surprising behaviour. This behaviour would need to be implemented in tikz-cd itself (making use of tikz-nfold), so that would be the appropriate place to report it; I'll close this issue.

(I suppose that if #3 is implemented, then double distance will automatically be set, which would mean no package error. A user would still have to use Rightarrow to get the correct arrowhead, but it would be an improvement.)
