Feature request - bill splitting

[PanderMusubi]

Describe the issue

Offer a bill splitting feature in (at least) the mobile app.

Expected behaviour

Enter an amount in EUR, USD or whatever (or even Gulden) and over how many people this amount should be split. The result will be the divided amount in Gulden.

Perhaps also show the divded amount in the original currency, for people who need to pay you but are not using Gulden.

Additionally, payments requests could be made to receive the amount in Gulden from other people.

Implementing this feature will make using Gulden for bill splitting easier for a bill that was just paid in euro or any other currency. Also it will help the introducing the use of Gulden.

When splitting bills at bars and restaurants in the Netherlands amongst friends, colleagues and family, the payment requests from traditional banks (such as Tikkie) are used a lot. Bill splitting in Gulden should be as easy or even more easy. This might also need a way to share a payment request via WhatsApp, Telegram and Signal instant message services.
