Add some Dancer2 plugins and their dependencies

```bash
MODULE_SECTION="Dancer"
```
Would work here.

Due to this line in the eclass
```bash
[[ -z "${SRC_URI}" && -n "${MODULE_AUTHOR}" ]] && \
        SRC_URI="mirror://cpan/authors/id/${MODULE_AUTHOR:0:1}/${MODULE_AUTHOR:0:2}/${MODULE_AUTHOR}/${MODULE_SECTION:+${MODULE_SECTION}/}${MODULE_A}"
```
