Custom Day Name Component Render

[selfesteemteam]

Is your feature request related to a problem? Please describe.
I'd like to be able to change the day name indicators to buttons to allow users to quickly select/deselect all of the corresponding days for the given weekday in a given month.

Describe the solution you'd like
A prop, similar to the other custom render props, to change how the week day indicators are rendered.

Describe alternatives you've considered
I've looked through the docs to see if this feature already exists and wasn't able to find it. I thought it may also be a part of the header that I could possibly change but I am unsure given the custom header examples.

I figured out how to do it with the formatWeekDay prop. It doesn't let me mess with the container the buttons are in but I don't really need more control than that.
