Refactor optional parameters to use None defaults #40

[Peter-The-Great]

This is to fix the #40 issue that I have with this library. This change could significantly help the application, just incase RIPE starts adding more fields to their results that will not yet be indexed by this library.

@Peter-The-Great thanks! I need to spend some time refactoring a lot of this use more modern tools as well.

Pydantic would probably make a much better fit here in general too.

That's totally up to you man, this was the only issue I had. And it works for me now on my fork. I wanted to use it in another project, but wasn't sure how long it would take to get a response. Thanks for the message!

All good. It's been a minute since I've dusted this off. I will work through getting the tests working again in general too. Thanks for the PR!

Tests pass other than coverage for 1 line. Merging to take the contribution and fix in the future.
