`-32700, Parse error shall be returned`

* [ws server]: fix bug in subscription response.

`.await` was missing in RegisteredSubscription::send() and no responses
were actually sent which this commit fixes.

* [client API]: export `WsSubscription`

* [examples]: use `localhost` instead of `127.0.0.1`

Hostname is required when using `wss` and `127.0.0.1` is not valid hostname.

* [examples]: add subscription example.

Fixes newly introduced bug that causes `register_subscription` to have

* [server raw params]: fix debug implementation (#137)

* [server]: simply raw params impl

Use debug implementation of `common::Params` instead of doing something
similar that doesn't work properly.

* [raw params]: derive `Debug` impl.

* [ws server]: parse subscription ID for unsubscription instead of hardcoding `JsonValue::Null` (#136)

* [ws server]: fix broken unsubscribe.

Try to parse the subscription ID as the first element of an Array or the `subscription`
field of an Object/Map.

If both of those fails then regard it as a error.

* fmt

* fix grumbles: remove space indentation

* fix(ws server): sub/unsubscribe to same method should generate an error (#140)

Subscribe and unsubscribe to the same method should generate an error, which this commit fixed.

* chore: add naive benches for request/response (#142)

Co-authored-by: Niklas <[email protected]>

* fix(ws server): remove faulty debug_assert (#145)

The code assumed that `subscription id` is still in `active_subscriptions` when the
connection was dropped.

The list of subscriptions (kept in raw server) are not notified when a client dropped its
subscription/unsubscribed thus it's possible that the actual subscriptions are closed before the
entire client was dropped.

* refactor: resultify API + some crate reorg (#144)

* [ws client]: resultify API and fix subscribe.

* The commit changes the API to return `Err` when it's possible and to not ignore underlying errors.
* Fix that `fn subscribe` doesn't accept the subscription and unsubscription to be same which causes
errors in the server.

* nits: Err::SubscriptionMetod -> Err::Subscription

* refactor(client): common error type

* refactor(http client): resultify

* refactor(common): rename common -> types..

This commit renames the `common module` to `types` and tries to distinguish the types that is
directly related to the `JSON-RPC v2 specification` from others.

Somethings are a little big sloppy named as naming is hard.

Also, as bonus a removed a bunch of needless stuff in http server related to subscription.

* fix(websocket client): drop subscriptions that can't keep up with the internal buffer size (#166)

* fix(ws client): drop subscriptions when full.

This commit changes the behavior in the `WebSocket Client` where each subscription channel is used in a non-blocking
matter until it is determined as full or disconnected. When that occurs the channel is simply dropped and when
the user `poll` the subscription it will return all sent subscriptions before it was and terminate (return None)
once it's polled one last time. Similarly as `Streams` works in Rust.

It also adds configuration for the `WebSocket Client` to configure capacity for the different internal channels to avoid
filling the buffers when it's not expected.

* tests(ws client): simple subscription test.

* Update src/client/ws/client.rs

Ensure that if more than the requested channel buffer capacity is exceeded it should not deadlock.
Such as spawning alot of concurrent requests, notifications or new subscriptions.

* fix(request manager): resultify insert API

The rationale behind this change is that the `insert_methods` takes ownership of the `send_back_oneshot`
and if the operation fails it should be propagated the frontend.

So returning the `Err(send_back_oneshot)` if it fails makes it possible.
