RFC6979 is defined in terms of integer operations, e.g.:
bits2intmodshrint2octets
Our implementation previously avoided committing to any particular big integer library since dsa used num-bigint-dig and ecdsa used crypto-bigint. However, dsa has been migrated to crypto-bigint (#906), which means we can use crypto-bigint as the common big integer library for both without issue.
