Next: not possible to programmatically deselect range calendar timeframe

[floteslof]

Describe the bug

There currently is no way to reset a range calendar to an unset state (without any range selected).

If you follow the stackblitz link below and click the "Clear days" button, nothing happens except a Object { start: undefined, end: undefined } message is logged.

I think this functionality should be there because the default state (with value not provided) is also without a selected range.

I delved a bit in the code and believe that the conditions in the $effect are the cause for this problem. The $effect only changes the value if value.start is set, removing the option to completely clear the range.
