Add Support for Multiple Number Formats (Comma or Point as Decimal Separator)

I'm writing to request enhanced support for various number formats in Numbr, particularly for the use of the comma as either a decimal separator or a thousands separator. Currently, the platform seems to predominantly support the format where a comma serves one specific role (as a thousands separator), which aligns with the practices of several regions. However, a significant portion of the global population uses a format where the comma acts as a decimal separator, leading to potential confusion and data interpretation errors.

I propose the introduction of functionality that allows users to choose their preferred number formatting style. This could involve toggling between:
- Point as a decimal separator _(and comma for thousands separator)_
- Comma as a decimal separator _(and point for thousands separator)_
