#### Testing the changes
- I tested the changes in this PR: **briefly**

The currently packaged matio release includes a number of vulnerabilities fixed
in in the latest version (see https://github.com/tbeu/matio/releases/tag/v1.5.18
and https://github.com/tbeu/matio/releases/tag/v1.5.22), so this PR should
probably be merged soon.
