feat: batch post results

[gluax]

Motivation

Batching means less calls = goodness.

Explanation of Changes

I moved the logic for posting a result and creating an event to a common function.
Handler is now implemented on the PostResult type to retain the post_result behavior.
Implements the PostDataResults method. I don't collect the events to avoid allocations.

Testing

Add new tests.

Closes #181.

I realized I need to name the events differently. I can also clean up the post-data results test helper a bit!

For the event @Thomasvdam do you have any preferences on how I name the events for batch posting? Or is it ok they are all still the same?

I don't really have an opinion on the events yet because I don't know how these show up in the block data 😬 I'm not relying on any of it so feel free to make changes.
