add calendar to exchange-calendars in python

There is a python package (exchange-calendars, https://pypi.org/project/exchange-calendars/3.3/) that provides trading calendars for various financial markets. It doesn't appear to support the Eurex. I would like someone to build a Eurex calendar that has the same class properties as existing calendar. The calendar should support the STOXX 50 index and its derivatives (https://www.eurex.com/ex-en/markets/idx/stx) and the VSTOXX index and its derivatives (https://www.eurex.com/ex-en/markets/vol/vstoxx). It should also include unit tests.
