Support for Multiple Calendars (e.g., Gregorian and Nepali)

[ghost]

Currently, ReportBro does not support multiple calendars, such as the Gregorian and Nepali calendars. I would like to inquire if this feature is already supported but perhaps I have overlooked it. If it is not supported, I would like to understand what changes would need to be made in order to incorporate multiple calendars into the library.

Ideally - I should be able to provide parameter on the backend like that will tell reportbro how to display the date - gregorian only, secondary calendar (using provided function with formatting) or both (so for example "07.02.2024 (24.10.2080)").

If this is not yet possible could you guide me and tell what would have to be reworked in the library if I were to create a proper PR?

Thank you for your assistance.
