Encpsulate the process in CWL

Put everything together according to Open Geospatial Consortium (OGC) [Best Practices](https://docs.ogc.org/bp/20-089r1.html).

Containerise processes and add them in a Common Workflow Language (CWL) pipeline.

Use [cwltool](https://cwltool.readthedocs.io/en/latest/) and [CWL documents based on OGC Best Practices for EO packages](https://docs.ogc.org/bp/20-089r1.html#toc24).
