This is part 1 of a stacked diff to remove a bch-api call from Airdrop.js

In this part, chronik is used to calculate the same information (i.e. the minting address). A console.log statement confirms that both methods get the same result.

The rest of this stack will deprecate the bch-api approach and remove debug logging.

npm start
Create an aidrop tx and hit the switch for 'Ignore eToken minter address', hit 'Calculate Airdrop' button
Observe the dev console for Chronik and bch-api got the same minting address statement
Confirm you get the same result for a handful of different token ids
