Methscan

This is a minor release that links our [publication](https://doi.org/10.1038/s41592-024-02347-x) and [website](https://anders-biostat.github.io/MethSCAn/) in the CLI help messages.
Furthermore, MethSCAn now prints an appropriate error message if you provide it with an empty bed file.

This is a minor release that adds three tiny features:

1. `methscan filter` can now filter in place, i.e. overwrite its own input directory with a filtered version of itself
2. `methscan scan` now aborts properly when no VMRs above the `--min-cells` threshold are found
3. Added a command to show citation info and a link to our paper.

This is the initial release of MethSCAn upon acceptance of our paper. The main difference is that we renamed the package from `scbs` to `MethSCAn`.
