Depending on rkv in a crate that also depends on lazy_static version 1.0.1 can cause the problem described in https://users.rust-lang.org/t/2018-edition-macro-ergonomics/18790 if the consumer causes rkv to also use lazy_static version 1.0.1. We should thus require that rkv use at least lazy_static 1.0.2.
