support for dates with dots and spaces

[atharmohammad]

Closes #1010 this will support dates such as 26 .10.21 or 26 . 10.21 , in date 26 . 10.21 the first period was getting removed in sanitization even when it was between numerals only(surrounded by spaces) which was not needed. that is why changed the period sanitization regex a bit
