v2.0.0

• Built with Xcode 15.0.1 and Swift 5.9.
• Support creating file-less in-memory databases, e.g. for caching and testing. To create one instead of a directory path pass memory: together with an identifier string when creating a Store:

  inMemoryStore = try Store(directoryPath: "memory:test-db");

  See the Store documentation for details.
• Change Store.closeAndDeleteAllFiles() to support deleting an in-memory database.
• Removed some deprecated APIs:
  • Removed findIntegers() for property query, replaced by find().
  • Removed find() of Box, replaced by all().
• Update to ObjectBox C API 4.0.0.
