Consider if migration to `axum-login` v0.7.0 is appropriate

[maxcountryman]

Hi there,

I'm reaching out because we've recently released axum-login v0.7.0. This release replaces axum-sessions with tower-sessions, eliminating potential deadlocking issues, but also reimagines the axum-login API.

Because this is a significant breaking change, it may not make sense for all applications to migrate. On the other hand, future development will be on this new API and so I want to make sure crate consumers are aware.

I'm also happy to help answer any questions or otherwise be of assistance to folks looking to migrate.
