MemoryAdapter class
A concrete implementation of CacheAdapter that uses an in-memory map for storage.
Example:
// Initialize the memory adapter
final adapter = MemoryAdapter();
// Store a value
await adapter.put('myKey', CacheItem<String>(value: 'myValue', expiry: DateTime.now().add(Duration(days: 1))));
// Retrieve a value
final item = await adapter.get('myKey');
print(item?.value);
