Line-break each argument in TS class constructor definitions

[richburdon]

Constructors allow direct setting of member variables, but these are obscured if left on a single line:

For example, in the block below it's easy to miss the key member variable.

export class TestPeer<M extends Model> {
  public timeframe = new Timeframe();
  public mutations: ModelMessage<Uint8Array>[] = [];

  constructor(public readonly stateManager: StateManager<M>, public readonly key: PublicKey) {}

  get model(): M {
    return this.stateManager.model;
  }
}

Versus this:

export class TestPeer<M extends Model> {
  public timeframe = new Timeframe();
  public mutations: ModelMessage<Uint8Array>[] = [];

  constructor(
    public readonly stateManager: StateManager<M>,
    public readonly key: PublicKey
  ) {}

  get model(): M {
    return this.stateManager.model;
  }
}
