Ability to shift period by custom length when clicking next/previous buttons

[aseychell]

When clicking on next/previous buttons, currently it is hardcoded to always shift the dates by the full timeFrameOverall period. Ideally, there is the possibility to override this period from outside of the component.

I'm referring to this part:

ngx-time-scheduler/projects/ngx-time-scheduler/src/lib/ngx-time-scheduler.component.ts

Line 235 in 511072d

nextPeriod() {

Currently, the nextPeriod is defined by the view of the scheduler. So the timeFrameOverall defines this.
