Feature request: Expose Parsers and Reporters as an API

[lirantal]

Is your feature request related to a problem? Please describe. I was thinking it would be great to expose the parsers and potentially reporters too as an API. It would really just require exposing them via the main export file for anyone wanting to use this as a lib instead of a CLI too.

Potentially later we can split to another package but should be an easy start just exposing them straight-out right now.

Describe alternatives you've considered Doing this is ugly and opens many potential issues in the future:

const parser = require('pie-my-vulns/src/Parsers/SeverityTypeParser.js');
