QDate: provide slot for individual days in month view

Is your feature request related to a problem? Please describe. There is a events property which allows to mark individual days in month view with colored underline. Unfortunately I would prefer to have a different mark for the event, Maybe even a badge with number of events in this particular day.

Describe the solution you'd like If there would be available a specific slot in QDate component, for rendering of individual days, I could make my events or days visualisation as I wish. Heck, I could even capture mouseenter events and display some kind of hint, tip i popup when user moves the cursor over specific day. I could even put in some days other QComponents.

Describe alternatives you've considered The only viable alternative as of today to display different day rendering and capturing mouse events on particular days is just using another component from another library or single Vue component. The available app extension QCalendar is too big for using - for example I need to just display different colors for particular days in UMD mode, where every kb counts.

Additional context This doesn't seem as overly complicated, but it could IMHO dramatically improve quality of life and possible use cases for Quasar as a machine for presentation data based on time.
