Allow manual input from keyboard for fast date selection

[smarques84]

For a power user I would like to let the user input the dates directly by keyboard, i think this would be a nice to have addition, we could use a prop to enable/disable this feature when using the component

Hey @smarques84,
sorry for the late response.
I quite like the idea. Not sure how complex it would be.
Also considered allowing horizontal day selection with arrow keys (←|→) some time ago, which would possibly interfere with this.
But the calendar component is also exported and it would be possible to support both use cases separately.
Currently I don't have enough time to look into it. Feel free to open a PR. I'm happy to assist with any questions / issues.
