General improvements to code structure

Description

Make the code base ready for future feature extension. As we get new processing blocks we need to clean up the structure of the code a bit.
Also added a .prettierrc configuration to ensure correct code styling is used. Added improved typings to some functions.

Completes

None. Future preparations.
