## Add meta data parsing
<!--
type: feature
scope: all
affected: all
-->

Add parser for meta data comment in changelog entry. The parsed data is available via the `meta_data` property of `ExtractVersion` after running `parse_changelog_completely` and is added to the `changelog.json` file. See #28

- bump `snippets2changelog` to 1.3.0 to have the snippets meta data added to the changelog entries
- update `examples/changelog.json` to contain meta data of latest changelog entry
