Clay pipeline v04

[yellowcap]

This is the version that has been used for #142

Updates include

• Tile size of 256 px
• Different sample source with more samples
• More human footprint focused sampling strategy (more urban, more agriculture)
• improved logging
• Fix one bug for when pixel spaces from S2 and S1 don't overlap

Looks good to me, in the next iteration, maybe we move all configurable options into a config.yaml file for data.

So we are not creating the job array anymore?

We are, but instead of running 2500 individual tasks, we are running one array job which bundles these subjobs into one parent. That is way easier to handle.
