[MonthPickerInput] Add excludeMonth

[davidchalifoux]

The DatePicker component has the excludeDate param. It would be great if this same idea was available on the MonthPicker component.
I'm thinking excludeMonth where you can pass a function to determine if a month is disabled.

You can do that with getMonthControlProps prop.

That's perfect, I missed that option in the docs. Thank you as always Vitaly!
