feat: add onBundle callback

[aeworxet]

This PR adds functionality, as well as an options object, for the bundle method, which consists of:

• The onBundle callback.
• The excludedPathMatcher callback.

Closes #346

[aeworxet]

This functionality mimics the onDereference callback along with the test, which is likely why the test fails: the bundle method should have different test conditions.

@jonluca, could you please advise what the test should be?

Hello,

The logic looks sound, I think you just need to fix the test comparison. The bundle traversal is stable, right? The tests aren't failing based on platform, so just make sure yarn test returns 100% on your local machine.
