0.7.0 Sendable structs
Convert the top level types KeyValueEncoder and KeyValueDecoder from class to struct so they can easily become Sendable without adding a lock. #11
UserInfo now requires any Sendable values preventing any non sendable values from crossing currency domains:
var userInfo: [CodingUserInfoKey: any Sendable]While these are API breaking changes the fixit is easy to convert let decoder to var decoder where required. Fixing the userInfo is possible with an @unchecked Sendable box, but this API is rarely used anyway.
