Adding collections from different chains in the same component

[sacha-l]

I would like to be able to view collections from different chains in my Uniquery app. This would imply that I could do something like:

# in my .env file
ADDRESS=JHfxh28HRxd5fSY97fFpPfFXHmGGFGctNNr9GvnnNeQPVkS
CHAINS=["ksm", "bsx"]

and customize the utils/indexer.ts file to be able to handle the indexers of the different chains.

Please help me figure this out :)
