renBTC issuance

my first adapter I counted renBTC supply and removed hardcoded decimals. comments welcome!

Hey, I think we discussed this on Discord, but I though I’d post here for record:

I don’t think this adapter fits in the “issuance” collection, as the supply of renBTC doesn’t represent issuance but rather bridged assets.

However, I’m interested in looking at the total value of tabled assets, so this could be useful for that. Let’s table this adapter until then.
