checkSlpBalanceBatch.js

/*
checkSlpBalanceBatch.js

A script to check the balance of a user-specified token ID at an array of SLP addresses

Inputs (see `User Input` below)
1) Array of SLP addresses to check balance at (specified as array of object wallets with key addr, `sweepableWallets`)
2) TokenId of token balance queried, `checkedTokenId`

Outputs
1) Total balance across all addresses of user-specified tokenId
