feat(ngx-conveyer): reduce view updates and fix outputs

[arturovt]

Had to remove @Directive -> outputs and switch to the explicit declaration because currently the template compiler is not happy. Event emitters also should be declared on the class when outputs is provided so it's actually easier to use the explicit @Output(...) declaration:

Hello @arturovt.

We appreciate your contributions to our components!

The outputs related issue you left seems to be an issue with a module we use. I think you can keep the original code by modifying ngx-conveyer.interface.ts as follows.

Before

import { REACTIVE_CONVEYER } from '@egjs/conveyer';
import { AngularReactiveAdapterResult } from '@cfcs/angular';

export class NgxConveyerInterface { }

// automatic reactive state, methods types
export interface NgxConveyerInterface
  extends AngularReactiveAdapterResult<typeof REACTIVE_CONVEYER> { }

After

import { REACTIVE_CONVEYER } from '@egjs/conveyer';
import { ReactiveAdapterResult } from '@cfcs/angular';

export class NgxConveyerInterface { }

// automatic reactive state, methods types
export interface NgxConveyerInterface
  extends ReactiveAdapterResult<typeof REACTIVE_CONVEYER, "ngx"> { }

We will fix this issue above. We'll also be happy to review the changes you've made. Thank you very much!

Alright, I'll revert my outputs updates and will add the ngx prefix.
