Allow unrestricted date ranges without min/max

[probablykasper]

min and max are non-nullable and have default values. Changing this would require a textbox for setting the year.

min defaults to The start of the year - 20 years and max defaults to The end of today: https://github.com/probablykasper/date-picker-svelte/blob/191284689f5f50e641193cf5dca57404b0d486bc/src/lib/DatePicker.svelte#L39-L42

From @3nematix in #41:

Another bug is that you can't even select any year before 2003 this works like a min date

It's not a bug, but agreed that it's not ideal for many use cases

Any updates on this?

No sorry, I don't expect to be implementing new features anytime soon unless there's a PR or someone becomes a GitHub sponsor
