Date pasting issue.

[devourer3]

Hi Keller,

I'm using the library well every time.

I found one minor bug and reported it.

For example, paste 2022. 12. 13 in Korea, it will be displayed as 2022. 12. 12.

The cause of this problem is assumed to be an error that occurs when the DateColumn or IsoDateColumn does not add the GMT value to the time when "new Date('2022. 12. 13')" is executed in the pasteValue.

On the other hand, enter "new Date('2022-12-13')", the GMT value is added to the time and displayed as a normal date.

Thus, If there is a value which is '2022. 12. 13' OR '2022/12/13', in the pasteValue function, please replace all of them in 2022-12-13 format.

To Summarize,

1. yyyy-mm-dd(O)
2. yyyy. mm. dd(X) -> replace yyyy-mm-dd
3. yyyy/mm/dd(X) -> replace yyyy-mm-dd

If you'd like, I'll proceed with a pull request.

Please refer to the video.
