The client webapp is expected to include a json-serialized version of its FeatureFlags in the `X-TensorBoard-Feature-Flags` header or the `tensorBoardFeatureFlags` query parameter. This middleware extracts the header or query parameter value and converts it into the client_feature_flags property for the DataProvider's Context object, where client_feature_flags is a Dict of string keys and arbitrary value types. In the event that both the header and query parameter are specified, the values from the header will take precedence. cCs ||_dS)zxInitializes this middleware.
