patched version mixed calendars Gregorian and Jalali

[mh-firouzjah]

hi 👋
I've used your code base and mixed it with another plasmoid called Persian Calendar
inorder to create a patched version that has persian Jalali dates and numbers together with the original Gregorian calendar.
it's not the best possible work around but it's working.
Thank you for this very useful and feature rich plasmoid.

my version is Event Calendar With Jalali Support
