I believe that listing the paths (in the sense of: concatenation of
arrows, with multiple different paths between the same vertices) should be
the job of the path-semigroup: After all, these are the elements of the
path-semigroup.
So, I would prefer to *not* add it as a new method of `DiGraph` (perhaps
calling it `all_quiver_paths()`) and of course I would prefer to *not*
override the `all_paths()` method of `DiGraph`, but I'd prefer to let it
be a `PathSemigroup` method.
