Closes #95

Hi @bastidest, thanks for this PR. I totally agree on the functionality, however I'd like to have a slightly different implementations. I would prefer to move the whole filter logic into lib/changelogGenerator.js and pass filter option to changelogGenerator.generateMarkdown() instead of marking changelog commits. WDYT?

e.g.

changelogGenerator.generateMarkdown(changelogCommits, {
  releaseName: "FooBar",
  customMarkdown: "lorum ipsum",
  messageRegex: ...,
  scopes: [...],
  ...
});

I very much agree. I was being cautious not to break anything and thought i could surgically insert the fix 🥷. I did it properly now and removed the "marking".

I was having a hard time tracing back all object fields, so I started documenting with JSDoc to assist the IDE.
