Need an input param for auto-focusing filter box

[blackblood19]

Right now, as soon as we open the select element, the filter box is focused. Is there any way to not do that?

@blackblood19 an option would be to add

@Input() disableInitialFocus: boolean = false;

and check for it in https://github.com/bithost-gmbh/ngx-mat-select-search/blob/master/src/app/mat-select-search/mat-select-search.component.ts#L292

would you like to add this and file a PR?

@blackblood19 version 1.4.0 contains an input @Input() disableInitialFocus to disable initial focusing of the input field.
