fix(deps): Update pdf2json to version 2 (#116)

By @copmerbenjamin:

* Update pdf2json to version 2
MozBlobBuilder is not defined in newer versions of node, pdf2json 2 resolves this but drops node versions below 14 (#101, #103, #114)

* BREAKING CHANGE: drop support for Node.js < 14

* Increase ecmaVersion, according to node.js version upgrade
