"Hi there! I've added a 'Custom Entity Name' feature to replace the previous 'Random Number ID or Default Entity Name'.

I thought this might be useful for users who want more control over naming their entities, and I hope it adds value to the project.
If you don't mind, could you take a look at the changes? I'd love to contribute to making ZNPCsPlus even better! ❤
Thanks for your hard work on this project!"
