v0.2.0

⚠️ Breaking Changes

• Redis and SQLx storages have a dedicated trait that needs to be implemented for your session data, rather than implementing TryFrom and TryInto. See the specific storage docs for more info.
• All built-in storages now use a consistent builder pattern for constructing the instances, similar to the fairing.
• Hashmap-like sessions need to implement SessionHashMap
• The storage module has been reorganized, with the traits available at the module level
• The SessionStorage trait’s delete function now accepts the deleted session data as an argument.
