};Many objects lacked the required extensions field, which is of type flat_set<static_variant<void_t>>. Added last field in the following operations and objects:

As an example of use extensions - asset_create_operation.
Of options fee in operations transfer_operation, override_transfer_operation, withdraw_permission_claim_operation field is removed price_per_kbyte.
Field is added to the sidechain::erc20_config erc20_config after sidechain_config.
