Global export of bsv undefined since 2.0.10

[libitx]

Since v2.0.10 tests in txforge are failing - re libitx/txforge#15

It seems the global export of bsv no longer exists if using es module syntax in node environments. eg:

import bsv from 'bsv'
console.log(typeof bsv) // => undefined

Possibly related to 42334f5 but unsure
