Broken urls when converting ipynb to markdown

[153957]

I have a ipynb (here: https://github.com/HiSPARC/infopakket/blob/d15cde4747efe42b129482c1a70c00ee47788bd3/notebooks/3_zenith_afhankelijkheid.ipynb ) which contains a few links. When converted to markdown using notedown (v1.5) the links are broken when the markdown is viewed on GitHub or when using the QLMarkdown Quick Look generator. In those cases the links contain the new line characters which are in the link because they are broken over multiple lines by notedown. See the output markdown here (from a slightly modified ipynb): https://github.com/HiSPARC/infopakket/blob/6d7803cbed7a6c2190ba671ed0d181d83053e7cc/notebooks/3_zenith_afhankelijkheid.md
