This proposal aims to increase the maximum number of HRMP channels from 10 to 30. Note that number of inbound and outbound channels are separate configuration and therefore this is a batch call to update both values.


Send a batch of dispatch calls.
Unlike `batch`, it allows errors and won't interrupt.

May be called from any origin.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then call are dispatch without checking origin filter. (This includes
bypassing `frame_system::Config::BaseCallFilter`).

- This proposal wants to increase the maximum number of HRMP channels from 10 to 30.
- HRMP channels are used for communication.
- Inbound and outbound channels are separate configurations.
- This proposal will update both values at the same time.
- The goal is to allow more communication channels to be used.
