Checklist

Please put "X" in the below checkboxes that apply::

• If committing a bugfix, I have tested it in different browsers (Chrome, Firefox, Safari).
• If committing a new feature, I have first submitted an issue (Please note: you are free to open PRs for non-issued features, but opening an issue increases your chance of a successful PR).
• If committing a new feature, I have also written an appropriate test suite for it.

I have tested the following:

• Qalendar component in month mode.
• Qalendar component in week mode.
• Qalendar component in day mode.
• All of the above modes on emulated mobile view.
• Dragging and dropping events.
• Resizing events in day/week modes.
• Clicking events to open event dialog.

This PR solves the following problem**.

Allows for more customization of the calendar. A fully custom header can be achieved by hiding the default one, calling for example @click="$refs.calendar.mode = 'month' to change mode, and with my pull request, utilize the existing goToPeriod method to change period rather than having to create a method that modifies selected-date.

I have run the existing Vitest suite, and I guess an improvement could be to create a test along with buttons in the same file as the Qalendar element, with the test running the method through the ref by clicking

How to test this PR**.

For example:

1. Add a template ref to wherever Qalendar is used
2. Create new buttons, with a click event that fires $refs.<refname>.goToPeriod('next') and $refs.<refname>.goToPeriod('previous')
