@lars-reimann could you please approve this pr and publish a new version of this project afterward? The current published version is from April so it misses the mnist datasets and supports safe-ds only up to version 0.21

[lars-reimann]

I'm closing this in favor of #203.

The upper bound must still be the next minor version, since releases of safe-ds with major version 0 might include breaking changes. We cannot guarantee that safe-ds-datasets is compatible with, say, safe-ds version 0.30.0.

I'll make a new release soon, though.
