Optimize resource storage memory

[atuchin-m]

The PR supports decoding resources before storing it. This optimize memory usage of ResourceStorage by ~30%.

• add a new ResourceImpl internal struct to store decoded resources
• validate each resource during initial loading
• support encoding a resource back to base64 when we need this (get_redirect_resource())
