What problem would this feature solve?

npm supports custom initializers to ease up setuping a package. If we add a package named @frctl/create-fractal, that could be used via npm init @frctl/fractal. This would essentially allow users to use the fractal new command without installing the @frctl/fractal package globally.

What the feature should look like?

Add a package named @frctl/create-fractal that does the same internal things that fractal new cli command does.
