Add referrer to token attributes

[boskiv]

Is your feature request related to a problem? Please describe. I want to see refer id in the token to understand who sells token to the user (marketing conversion rate calculation) We have a vast partner network and expect a thousand sales(minting tokens) per month. We want to know a partner conversion and display it on or partner's website for us and the partners themselves.

Describe the solution you'd like One of solution can be add refer to token attributes with new trait type refer

{
"name": "Unlock Key",
"description": "A Key to an Unlock lock. Unlock is a protocol for memberships. https://unlock-protocol.com/",
