Reconsider default setup

[AloisSeckar]

Following "default" integrations inflate the bundle size quite a lot. It should be re-considered, whether to include (all of) them by default or let users decide whether they need them:

NUXT_PUBLIC_IGNIS_DEFAULT_IMAGE=false
NUXT_PUBLIC_IGNIS_DEFAULT_SCRIPTS=false
NUXT_PUBLIC_IGNIS_DEFAULT_SECURITY=false
NUXT_PUBLIC_IGNIS_DEFAULT_AUTH=false

This reduced Σ Total size: 28.4 MB (10.7 MB gzip) down to Σ Total size: 3.76 MB (971 kB gzip)

I am thinking about introducing "security" module and make nuxt-auth-utils and nuxt-security opt-in

Observation:
The bloat is mostly caused by @nuxt/image` alone.

Adding it as a module results into sharp runtime being added into server-side bundle being about 24MB larger...
