Added first simple version of CLI script.

This PR adds a command line interface for calling readers. At the moment, this doesn't work due to non-merged PRs on spatialdata-io.

These are the things that still need to be done in this code to make it work:

• Add flags for each specific technology to ensure all of them work
• Wait for PR Mcmicro update #28 to be merged

Thanks @FloWuenne for the contribution! I marked the PR as draft for the time being.

@HelenaLC tagging you here since so you know when this PR is merged.

• I am also going to update the docs to explain how to use the CLI commands, I will add the link in a comment when it's ready so that you can add it in your docs.
