Hello, is there a reason that SparseMap doesn't impl std::fmt::Debug and/or Default? I would like to use it inside my own data structures that derive those impls.

(I read these contribution guidelines which encouraged me to open an issue, please let me know if there's a more appropriate place to ask, thanks!)

This seems like a reasonable contribution to make -- I'd be happy to review a PR if you'd like to do this! The only thing I'd note right away is that we don't want to constrain K: Debug and V: Debug unconditionally -- let's have a trait impl that provides Debug if they both have that impl.
