Add support for helm plugins

[lorf]

Is your feature request related to a problem? Please describe.

We have several helm charts created inhouse, that extensively use helm plugins (notably, https://github.com/jkroepke/helm-secrets and https://github.com/mumoshu/helm-x) to extend helm capabilities. Helmwave, to my knowledge, does not support helm plugins, so we cannot use it with our charts.

Describe the solution you'd like Add support for helm plugins to helmwave.

Describe alternatives you've considered I don't see any way we can use helmwave without support for helm plugins implemented.
