[Feature Request] Enhancing Gringotts with Multiple Currency support

[iomatix]

I’ve been an user of the Gringotts plugin, and I truly appreciate the immersive economy experience it brings to the server.

I would love to see the addition of support for multiple currencies with their respective denominations, similar to the existing functionality for a single vault.
I understand that the integration with Vault might be a consideration for this feature. I am not entirely sure if Vault allows for such a capability.

I kindly request you to take my suggestion into consideration. I believe that adding multiple currency support would solidify Gringotts as the go-to choice for RPG servers seeking a comprehensive and customizable economy system.

Thank you for your time and dedication to making Gringotts an exceptional plugin. I look forward to hearing your thoughts on this feature request!

Is your feature request related to a problem?

It's only immerssive thing for avoiding problems with making multiple currencies using denomination system like:

• Paying with Emeralds but getting Iron back for a change.
• Griefing and destroying economy

Describe the solution you'd like

Adding possibility to create and configure next currencies with their denominations.
So e.g. Emerald -> Emerald Block, Gold Nugget -> Gold Ingot -> Gold Block are not considered as the same currency
so if something costs in Emeralds player can not pay with the gold but if something costs in gold player can not pay with the emeralds etc.

Describe alternatives you've considered

Using denominations system but it's not so effective and has its problems.
