v0.11.0-beta

We have a big release for you today :tada: :tada: ! We're including some big performance improvements :zap: and long-awaited bugfixes :lady_beetle:! Remember to stay tuned for our 0.12 release soon.

This release includes some major breaking changes, so **you won't be able to use your old databases with this version**. Run `spacetime local clear` to remove them.

# Important changes
## Major
- :zap: We removed our usage of protobuf, in favor of our own internal format (#1077) - this is a **big** performance improvement on the client and the server!
- :hourglass:  We removed the server-side `schedule!` macro and its equivalents in favor of table-based timers  (#1449). Please check our [server module docs](https://spacetimedb.com/docs) for more info on how to use the new system.

Here is some example code which uses the new timer tables:
```rust
// The `scheduled` attribute links this table to a reducer.
#[spacetimedb(table, scheduled(send_message))]
struct SendMessageTimer {
    text: String,
}

// Reducers linked to the scheduler table should have their first argument as `ReducerContext` 
// and the second as an instance of the table struct it is linked to.
#[spacetimedb(reducer)]
fn send_message(ctx: ReducerContext, arg: SendMessageTimer) -> Result<(), String> {
    // ...
}

// Scheduling reducers inside `init` reducer
fn init() {
    // Scheduling a reducer for a specific Timestamp
    SendMessageTimer::insert(SendMessageTimer {
        scheduled_id: 0,
        text:"bot sending a message".to_string(),
        //`spacetimedb::Timestamp` implements `From` trait to `ScheduleAt::Time`. 
        scheduled_at: ctx.timestamp.plus(Duration::from_secs(10)).into()
    });

    // Scheduling a reducer to be called at fixed interval of 100 milliseconds.
    SendMessageTimer::insert(SendMessageTimer {
        scheduled_id: 0,
        text:"bot sending a message".to_string(),
        //`std::time::Duration` implements `From` trait to `ScheduleAt::Duration`. 
        scheduled_at: duration!(100ms).into(),
    });
}
```
