Make it more flexible for users to select which version of `async-std` to use.

The reason is that `Receiver::next` won't panic polling after `Ok(None)` has been received.

* [deps futures]: remove unused features

I got annoyed that we bring in `futures-executor` as a dependency however `soketto` does this too, so doesn't help
for the `WS` stuff.

* cargo fmt

* add wrapper crate

* add jsonrpsee crate back

* [jsonrpsee]: feature gate modules

Use futures::channel::mpsc as it's already brought in as dependency and to avoid bring
in tokio sync as an additional dependency.

* remove unused deps/code

* fix nit

* [utils]: future mpsc works without alloc.

* fix bad merge

* [client]: batch request generic response

* wait with impl

* [ws client]: add template for batch requests

* remove jsonvalue

* naive impl

* fix make it work,

The implemenation is quite inefficient because the responses might be unordered.
Currently, a "digest" of a BTreeSet is stored to sort the requestIDs
and don't have to try all combinations of requestIDs in the response.

* fix nits

* error handling

* fix nits

* more nits

* use error msg pattern

* add batch requests to client trait

Keep it simple by require `Vec<(Method, Params)>` could be improved.

* address review comments: use swap_remove

Replace read values with `Vec::swap_remove` instead inserting dummy value.
The reason is that `Vec::remove` is O(n)

* address review grumbles: batch trait bound Default

* don't be clever

* [http client]: faster lookup for batch request.

* fix: distguish request_id and batch_id

* thanks clippy

* fix: clarify bad response with a separate error

* fix tests

* add issue link to todo

* Update types/src/error.rs

* [ws client]: unsubscribe directly

When a subscription is dropped because of `max_notifs_per_subscription` is exceeded
the client didn't send an `unsubcribe request` until the subscription was dropped which this commit fixes.

This causes the server to still send messages to the subscription and the client would get lots of
error messages `InvalidRequestId`

Breaking change which removes the `Clone` on the `WsClient`.
