Implement CAIP-19 - neume IDs

[reimertz]

We currently create our own ID mapping combining address and tokenURI for each track generated by neume.

Preferably, neume would do this and include an id entry in the schema

Example: Sound.xyz Snoop Dogg Death Row Session: Vol. 2 (420 Edition) #563

Reference: CAIP-19

Great idea. Additionally, within neume-network/schema we could ask for a string to have a certain "format" or "pattern" using e.g. a regular expression put forth by CAIP

I transferred this issue to the schema repository to get started on it by defining how an ID could be included into the schema. The data itself, e.g. the collection's address and tokenID, we already have in the strategies...
