further work

Following improvements are planned for development:

1. Support for two more method types:

• method with default return without acknowledgment - its future will return as soon as request message is sent to producer without waiting for () response from the producer:

  #[no-ack]
  async fn do_something_i_dont_care_if_it_completes(&self, some_argument: i32);

• method with CancellationToken argument - so producer implementors can receive request abort messages (currently "aborting" a request means only that the producer will ignore task's result and not send it to the consumer - it doesn't mean the task itself is meaningfully affected):

  use tokio_util::sync::CancellationToken;
  
  // ...
  
  async fn do_some_task(
      &self, 
      cancellation_token: CancellationToken, 
      some_argument: i32) -> u64;

  Of course consumer method would not have cancellation_token argument:

  fn do_some_task(&self, some_argument: i32) -> zzrpc::ValueRequest<u64, Request, Self::Error>;

2. An option to generate bindings so consumer methods could be called directly from JavaScript using wasm-bindgen.
