express-prom-bundle 6.3.2

on Node.js NPM

• peer dependency prom-client set to >=12.0.0 instead of ^13.0.0 (it was a regression), thanks to @billyjanitsch

Minor dev changes:

• travis now run tests on node 14 instead of 13
• added eslint test to travis build
• dtslint now tests only the latest TS version on travis. This was a workaround for dtslint failing on travis when referencing types for prom-client in older versions of TS
