Native Caching

[merren-fx]

Initial Checks

• I have searched Google & GitHub for similar requests and couldn't find anything
• I have read and followed the documentation and still think this feature is missing

Description

Since we want to move away from DVC there is a need for native file-system based caching.

The BaseStepExecuter needs to be extended to accomodate the following features:

1. On execute_step check if inputs have previously been seen
2. If so don't do anything
3. If not run step
4. Cleanup of old outputs (Problem: a previously executed step

Wurzel CLI needs to be extended to also accept a list of files as input, so that we can do caching based on either folder or file base
