=== Asynchronous Get -- local ===

# Get(id, sender, callBack)
# Check m_Cache.GetFromMemory() -- invoke callback immediately if found or negatively cached
# UUID.Zero check -- invoke callback with null and return false
# Lock m_AssetHandlers:
#* If request already in-flight for this id: append callback to handler list, return
#* Otherwise: create handler list, add to m_AssetHandlers, enqueue id to m_localRequestsQueue
# AssetRequestProcessor dequeues, calls Get(id), notifies all handlers via FireAndForget
