Feature Request: Add Support for Persian Calendar

[ghost]

I would like to request a new feature to support the Persian calendar in moeGramX.

Adding support for the Persian calendar would make moeGramX more inclusive and accessible to users from Iran and other countries that use this calendar system. It would also help to improve the overall user experience and make the app more useful for a wider range of users.

For an implementation example, check out Nekogram x(it's based on stock telegram) support for Persian calendar.
