Breaking

• Require Node.js 10 80165c1

Breaking for TypeScript users

• Only use a CommonJS export for the TypeScript definition (reason)
  You need to change import getStream from 'get-stream'; to import getStream = require('get-stream');

Improvements

• Use native stream.pipeline instead of pump package (#39) 5cf31ba
