Outfactor shared logic in input components

[XanderVertegaal]

Okay, considering the exportResult function from spindle.component.ts:

public parse(): void {
        this.form.controls.mpInput.markAsTouched();
        this.form.controls.mpInput.updateValueAndValidity();
        const input = this.form.controls.mpInput.value;
        if (this.form.invalid || !input) {
            return;
        }
        this.apiService.input$.next(input);
    }

These functions are very similar: could we think of a good way to make them generalizable / put them in a service? Is that even worthwhile, do you think? I'm happy to let this rest since it's not really priority but I was wondering all the same.

I'd consider the SpindleAPIService and MpAPIService for this. Both implement ParsePortDataService; maybe we can add more shared logic to that.
