This commit adds an optional argument in the `random_walk` function, namely `return_edge_indices`. The default behaviour is not changed, but if a user wants to directly use the edges visited by the random walker, we can return the indices of those edges by setting `return_edge_indices` to `True`. New cases are also added to the test suite.

This PR addresses the feature request in #137. The changes can be easily ported to
pyg-lib(at least in theory 😅 ), but currently, we still rely ontorch_cluster, so I added the change here first.This commit adds an optional argument in the
